dpotted by Arun Lakhana
- added: docs for tools and safe_print_to_file
- added: support for XPath variables
thanks to Nathan Glenn for the initial implementation
- updated: Changes to conform to CPAN::Changes + test
3.44 - 2013-05-13 - minor maintenance release
- added: XML::Twig::Elt new method now acccepts literal content, eg
my $e= XML::Twig::Elt->new( '<div><p>foo</p><p>bar</p></div>');
- added: twig handler triggers now accept the syntax <tag>#<id>
use *#<id> if you don't want to specify the tag name (#<id> would not
work since this is the syntax for "private" elements, this makes it
ugly, but is due to the fact that when I started working on XML::Twig
CSS wasn't really around)
- fixed: merge had some problems dealing with embedded comments
- improved: more tests
- improved: make Changes conform to the CPAN::Changes spec

and $elt->children( 't1|t2')
- added: the discard_all_spaces option that discards more aggressively
non-significant white spaces
see RT #71164 https://rt.cpan.org/Ticket/Display.html?id=71164

version, to avoid bugs in the original version and improve
stability of the output
3.39 - 2011-09-22 - minor maintenance release
- fixed: xml_pp -i would blank all files after the first one
thanks to dvercande for spotting this
- added: findvalues method (XML::Twig and XML::Twig::Elt)
same as findvalue except that it returns an array of value

outputs the DOCTYPE declaration for HTML docs converted
by HTML::TreeBuilder (fixing it if necessary)
see RT #71009: https://rt.cpan.org/Ticket/Display.html?id=71009
- fixed: t/test_autoencoding_conversion.t failed with $PERL_UNICODE
set to SA* (which prevents autoconversion)
reported by Martin J Evans, RT #71084
https://rt.cpan.org/Ticket/Display.html?id=71084
3.38 - 2011-02-27 - minor maintenance release
- fixed: RT 65865: _ should be allowed at the start on an XML name
https://rt.cpan.org/Ticket/Display.html?id=65865
reported by Steve Prokopowich
3.37 - 2010-10-08 - minor maintenance release
- fixed: more tests fixed for HTML::TreeBuilder, hopefully
will pass now
- changed: making att and class lvalues created problems: in certain
context they made regular calls to the method create empty
attributes. I could find no satisfactory fix,they were either
incompletes, or to complex for often used methods. So att and
class are back to being regular, non l-value methods.
latt and lclass are the l-value versions.
- added: documented the -html option for xml_grep, that allows processing
HTML input
- added: the -Tidy option to xml_grep, that uses HTML::Tidy to convert
HTML to XML
3.36 - 2010-10-07 - minor maintenance release
- added: the use_tidy option to XML::Twig->new, which uses
HTML::Tidy to convert HTML to well-formed XHTML, as an
alternative to the default conversion which uses
HTML::TreeBuilder
- added: XML::Twig::Elt method siblings which returns the
siblings of the element
- added: methods att_accessors, elt_accessors and field_accessor
as well as the similarly named options when creating an
XML::Twig
- added: set_outer_xml XML::Twig::Elt method
- added: print_to_file on an XML::Twig::Elt
- added: can use the tag[nested] form in twig handlers that
triggers on elements 'tag' that include a child 'nested'
- added: aliased the add_to_class XML::Twig::Elt method to add_class,
which seems more natural
- added: the remove_class method
- added: made att and class lvalues (in perl 5.6 and up)
- fixed: copy did not copy the empty status of an element
RT#31664 spotted by Roland Minner
https://rt.cpan.org/Ticket/Display.html?id=31664
- fixed: cut_children would always set the empty status of an element,
even if it had children left
- fixed: tests did not pass with HTML::TreeBuilder 3.23_1 due to a
change in an error message
3.35 - 2010-05-15 - minor maintenance release
- added: the by_file option to xml_grep that limits
the number of hits per file
- added: allowed the text of ignored elements to be buffered
in a string
- fixed: comments need to be escaped (you can't have 2 '-' in a
row), RT#57389 spotted by Konstantin Tchernov
https://rt.cpan.org/Ticket/Display.html?id=57389
- fixed: after $elt->cut_children, $elt->empty is false RT#54570
spotted and patched by Andrew Pimlott
https://rt.cpan.org/Ticket/Display.html?id=54570
- fixed: documented the fact that latin1 is ISO-8859-15, see RT#37431
https://rt.cpan.org/Ticket/Display.html?id=37431
3.34 - 2010-01-18 - minor maintenance release, test suite fixes
- fixed: tests failed when XML::XPath was used as the XPath engine
3.33 - 2010-01-15 - minor maintenance release, bug fixes
- added: XML::Twig::Elt method att_exists which returns true if the attribute
exists in the XML
- added: XML::Twig::Elt method lc_attnames which lower cases the names
of all the attribute of the element
- added: better error message if find_nodes or get_xpath are called instead
of findnodes when using XML::Twig::XPath (suggested by Zed Pobre)
- added: indented_close_tag pretty_print option (suggested by H.Merijn Brand)
- added: RT #49692 xml_split test on win 32 systems. Patch sent through RT
http://rt.cpan.org/Ticket/Display.html?id=49692
- added: using position selector (eg foo[2]) in handler triggers now raises
an error, spotted by Selvakumar
- added: you can use css like selectors for class in navigation: 'p.title' will
select p elements with a class that contains title.
In order to preserve backward compatibility and to allow the use of
elements with a dot in their name, if there are already parsed elements
with a tag name of 'p.title' then they will be selected instead
- added: you can also use css class selectors in trigger handlers.
- fixed: avoids expat (and XML::Parser) "Ran out of memory for input buffer"
error, and instead reports an "empty file" error (and does not attempt
to parse the file).
- fixed: RT #51432 attributes containing quote character don't escape properly
found, and patch provided by Jeremy Kahn
https://rt.cpan.org/Ticket/Display.html?id=51432
- fixed: RT #48616 handler condition of foo/* crashed the module
reported by Osfameron
http://rt.cpan.org/Public/Bug/Display.html?id=48616

https://rt.cpan.org/Ticket/Display.html?id=33269
found by Hermann Peifer
- fixed: xml_split bug when using an XML declaration and a utf8 encoding. Spotted
by Chris Price.
- fixed: xml_pp bug, pod2text command to display help was not properly quoted.
Spotted by Chris Price.
- fixed: failing tests when LWP::UserAgent is not available
- fixed: RT #41147: use of uninitialized value in eval when attribute isn't found
reported by Zed Pobre
http://rt.cpan.org/Ticket/Display.html?id=41147
- fixed: memory leak when the XML included id's
- fixed: XML::Twig::Elt->set_content fails when argument is 'XML::Twig::Elt'
(or the name of a subclass of XML::Twig::Elt)
http://rt.cpan.org/Ticket/Display.html?id=40399
- fixed: bug RT #39849, set_output_encoding( 'utf-8') did not work quite right
on filehandles that were already open in >:utf-8 mode
spotted by Zed Pobre
http://rt.cpan.org/Ticket/Display.html?id=39849
- fixed: xml_pp now accepts all formating options available in XML::Twig
- fixed: RT #31664, element attributes are not preserving their order when
using elt->copy spotted, and fix provided by jbubbabrown
- fixed: RT #31832, wrapped link to xmltwig.com in L< > tag in the doc
spotted by Slaven Srezic
http://rt.cpan.org/Ticket/Display.html?id=31832
- fixed: RT #31833 doc fix, spotted by Slaven Srezic
- fixed: Makefile.PL doesn't nag the poor tester anymore when running with
$AUTOMATED_TESTING set
- fixed: bug calling set_text when using XML::Twig::XPath, spotted by Ted Sung
- fixed: improved speed when parsing big elements, RT#35672, reported by Seth
Viebrock (fi is to explicitely return null from the character handler,
instead of the text already parsed... a few hundred thousand times)
http://rt.cpan.org/Ticket/Display.html?id=35672
- fixed: RT #47257, minor doc bug, spotted by David Steinbrunner
http://rt.cpan.org/Ticket/Display.html?id=47257
- fixed: bug in navigation conditions of the form elt[text()=~ /text with 'or' or 'and'/]
- improved: speed, somewhat
-improved: put the project on github: http://github.com/mirod/xmltwig
3.32 - 2007-11-13 - minor maintenance release with a bug fix
- fixed: change to the regexp that parses XPath-like conditions so
it can accept leading non-ascii letters ([^\W\d] does not
work), not used in perl 5.005
- fixed: set use utf8 (except in 5.005), which gets rid of the dreaded
"SWASHNEW" error in 5.6.*, fixed things that then broke in 5.6.
3.31 - 2007-11-07 - minor maintenance release, fixing some tests
- fixed: fixes to stop tests from failing in various configurations
3.30 - 2007-11-06
- fixed: a couple of bugs in namespace handling, spotted by
Shlomo Yonas (see https://rt.cpan.org/Ticket/Display.html?id=27617
and http://www.perlmonks.org/?node_id=624830)
- added: the XML::Twig::Elt fields method which returns a list of
fields
- added: the normalize method in XML::Twig and XML::Twig::Elt,
which merge together consecutive pcdata elements. As much as
possible (so far after a cut, delete or erase), the twig is
kept normalized, eg there are no consecutive #PCDATA elements
in it. Suggestion of someone whose name (and emails) I can't
find at the moment.
- added: the indented_a / cvs format for pretty_print, that makes the
output friendly to line-oriented version control tools, as described
in http://tinyurl.com/2kwscq (RT #24954). Thanks to Sjur Moshagen
for a patch that I adapted to the current version.
- fixed: bug RT #25113: system entities were not properly resolved
if the XML file was not in the current directory. Thanks to
Dave Charness for the patch.
- added: the XML::Twig method finish_now that terminates parsing
immediately, without checking the rest of the XML. This feature was
half suggested by Nick Clayton
- added: the -s option to xml_split, which splits when the given
size is reached for a file, suggested by Radek Saturka.
- added: the -g option to xml_split, which groups elements to be
split, suggested and tested by Dhirendra Singh Kholia.
- added: the safe_parsefile_html and safe_parseurl_html methods,
and a --html option to xml_grep. Suggested by Bill Ricker.
- improved: by default xml_grep now skips non well-formed files, the
--strict option makes it die when it finds one
- fixed: a bunch of bugs in xml_grep
- fixed: a warning when using optional modules with a version
number that includes an _, spotted and fix suggested by
Bill Ricker.
- fixed: test failure on cygwin, thanks to Erik Rantapaa for the
patch.
- fixed: a bunch of typos in docs, RT #25836, spotted and fixed by David
Steinbrunner
- improved: re-use of XML::Twig objects for repetitive parsing. It
looks like it should be OK now , but I am sure I haven't tested
all cases yet (especially when DTDs and entities are involved).
- improved: HTML parsing; XML::Twig now tries to find the proper
encoding for the document (that's not done by HTML::TreeBuilder
at the moment).
-fixed: XML::Twig::Elt purge and flush methods now only purge/flush up to
the element, not up to the current element in the twig (duh!)
- fixed: bug in handlers of the form elt[string(subelt)="foo"] and
elt[string(subelt)=1] which did not work at all
- fixed: bug in parameter entity output, spotted by BenHopkins on
perlmonks (see http://www.perlmonks.org/?node_id=618360)
- fixed: bug in xml_string: options were not used
- improved error reporting for missing SYSTEM entities, including
the option to set twig_expand_external_ents to -1, which makes
missing SYSTEM entities not fatal, but reports them in
$t->{twig_missing_system_entities} Thanks to Frank Wegmann for
his suggestions and for testing the various versions of the feature
- fixed: internals so new versions of Pod::Coverage won't barf
3.29 - 2007-01-22
- fixed: a bug in the handling of handlers after an ignore (RT #24392,
reported by Robert Eden).
3.28 - 2007-01-05
- now builds on Windows and OS2
- improved: refactored the code that triggers handlers,
more complex expressions can now be handled,
such as '/doc/section[@def="1"]/title'
- COMPATIBILITY WARNING
Up to version 3.26, you could change the attribute
of a parent of a node on which you had a handler,
and be able to trigger a handler on that parent node
based on the new attribute value:
XML::Twig->new( twig_handlers =>
{ 'sect/title' => sub { $_->parent->set_att( has_title => 1)},
'sect[@has_title="1"]'=> sub { ... }, # called for any sect that has
} # a title
);
This won't work now. The trigger expression ('sect[@has_title="1"]')
is evaluated strictly against the input XML. This is more logical and
consistent (if you changed the element name, the new name was never
used in the evaluation of the trigger).
The only exception to that rule is if you use "private attributes":
attributes which name starts with a '#'. By definition this in an invalid
XML name, so it can't be in the input, and has to have been created . In
that case the code that evaluates the trigger looks at the attribute in
the element in the tree in memory (if it exists).
So in the example above, if you replace 'has_title' by '#has_title',
everything will work fine. Note that private attributes are not output
when using the print/sprint/xml_string... methods.
- fixed: xml_pp so it does not leave a tempfile
and a broken original file all when the original
file is not well-formed.
- added: the nparse_pp method that does an nparse
with pretty_print set to 'indented', nparse_e
that sets error_context, and nparse_ppe that
does both
- added: XML::Twig::Elt tag_to_span and tag_to_div
methods (turn an element into a span/div and
set its class to the old tag name)
- added: the quote option for XML::Twig new, which
sets the output quote character for attributes
('single' or 'double')
- added: the text_only and xml_text_only methods
that return the text of the element, but not of
the sub-elements.
- added: outer_xml method (synonym for sprint)
- fixed: bug where entity names were not matched
properly (RT #22854, spotted by Bob Faist)
- fixed: bug on some DOCTYPE config with
twig_print_outside_roots
- fixed: bug in set_keep_encoding (the method,
not the option).
- fixed: bug in simplify: the code attempted to
replace variables in attribute values even if no
option required it, spotted by Klaus Rush
- improved: clean-up and fixed bugs in ignore: the method
can now be called from a regular handler (it
always could but the docs did not say so,
thanks to kudra for noticing this). It can
also be called to ignore a parent of the current
element. There were bugs there, and the tree
was not built properly
- added: error message when an XPath query with
a leading / is used on a node that does not
belong to a whole twig (because it's been cut
or because the twig itself went out of scope)
- improved: when parsing HTML with error_context set, the
HTML is indented, in order to give better error
report
3.26 - 2006-07-01
- added: argument to -i in the Makefile to prevent
problem in win32
- added: XML::Twig::Elt former_next_sibling,
former_prev_sibling and former_parent methods
- squashed a memory leak when parsing html
(forgot to call delete on the HTML::Tree object)
- fixed: bug that caused XML::Twig to hang if
there was a syntax error in a predicate
(RT#19499, reported by Dan Dascalescu)
-improved: made start_tag and end_tag more consistent: they
now both return the empty string for comments,
PIs... (reported by Dan Dascalescu)
- added: parsefile_inplace and parsefile_html_inplace
methods (thanks to GrandFather on perlmonks)
- added: support to add css stylesheet in the
add_stylesheet method (thanks to Georgi Sotirov)
- patched tests to work on Win32
- added: set_inner_xml inner_xml and set_inner_html
methods
3.25 - 2006-05-10
- patched to work with perl 5.005!
- fixed: a bug in xml_pp when pretty printing a
file in place in a different file system
3.24 - 2006-05-09
- added: loading the text of entities stored in
separate files (using SYSTEM) when the (awfully
named!) expand_external_ents option is used.
Thanks to jhx for spotting this.
- changed: set_cdata, set_pi and set_comment so that
if you call them on an element of the wrong kind,
everything works as expected, instead of swallowing
silently the data. Bug spotted by cmccutcheon
- fixed: a whole bunch of things to make the module
run and the tests pass on VMS, thanks to Peter
(Stig) Edwards who reported bug RT #18655 and
provided a patch.
- fixed: bug on get_xpath( '/root[1]') expressions,
RT #18789 spotted by memfrob.
- added: the add_stylesheet method, that... adds a
stylesheet (xsl type is supported, let me know if
other types are needed) to a document.
- improved: allowed pasting PI/Comment elements before or after
the root of a document (see discussion at
http://perlmonks.org/index.pl?node_id=538550).
Thanks to rogue90 for noticing the problem, and to
Tanktalus for finding the best way to solve it.
- added: aliased unwrap to erase (ie added the unwrap method
to XML::Twig::Elt, identical to the existing erase)
suggested by Chris Burbridge.
- fixed: bug RT #17522: flushing twice at the end of
the the parse would output the last fragment twice.
Spotted by Harco de Hilster.
- fixed: bug RT #17500: parsing a pipe when using
the UTF8 perlIO layer (through PERL_UNICODE or -C)
now raises an error, found by Nikolaus Rath.
cwimproved: made the tests pass when the UTF8 perlIO layer is
used. At this point potential problems when parsing
non-UTF8 XML in this configuration are not trapped.
3.23 - 2006-01-23
- added: autoflush: there is no more need for the
last $twig->flush after the parsing, it is done
automatically at the end of the parsing, with the
same arguments as the first flush on the twig.
This can be turned of by setting $twig->{twig_autoflush}
to 0.
WARNING: if you finished the output with a direct
print instead of a flush, then this change will
cause a bug. Hopefully this should not be the case
and is easily fixable.
- fixed: bug RT #17145 where get_xpath('//root/elt[1]/child')
would produce a fatal error if there were no elt
element under root. Spotted by Dan Dascalescu.
- fixed: bug RT #17064 (comments and PIs after the
root element were not properly processed), spotted
by Dan Dascalescu.
- fixed: bug RT #17044: the SYSTEM value was not
output in UpdateDTD mode, thanks to Michal
Lewandowski for pointing this out.
- changed: the way empty tags are expanded with the
'html' style: only tags that are allowed to be
empty in XHTML are output as '<tag />', thanks
to Tom Rathborne for proding me to look into this.
- added: a 'wrapped' pretty_print option, that is
a bit dodgy I think but that might please some.
- fixed: bug RT #16540 (tags with specific names
(like 'level'), tripped XML::Twig, spotted by
Graham
- added: comparison with XML::LibXML in the SEE ALSO
section (and in the FAQ), following a question
from surf on c.l.p.m
- added: XML::Twig now rejects string/regexp condition
in twig_roots
- added: better error checking in xml_grep
- fixed: string/regexp condition in xml_grep
- added: support for ! @att (or not @att) in get_xpath
- added: support for several predicates in get_xpath
(not nested predicates though).
- fixed: bug RT #15671 (wrong condition interpretation
for attribute value 0)
- added: XML::Twig print_to_file method
- added: XML::Twig::Elt methods: following_elt,
following_elts, preceding_elt, preceding_elts
(needed to support the corresponding axis in
get_xpath)
3.22 - 2005-10-14
- added: the XML::Twig xparse method, which parses
whatever is thrown at it (filehandle, string,
HTML file, HTML URL, URL or file).
- added: the XML::Twig nparse method, which creates
a twig and then calls xparse on the last parameter.
- added: the parse_html and parsefile_html methods,
which parse HTML strings (or fh) and files
respectively, whith the help of HTML::TreeBuilder.
the implementation may still change. Note that
at the moment there seems to be encoding problems
with it (if the input is not UTF8).
- added: info to t/zz_dump_config.t
- fixed: a bug that caused subs_text to leave empty
#PCDATA elements if the regexp matched at the begining
or at the end of the text of an element.
- fixed: RT #15014: in a few methods objects were
created as XML::Twig::Elt, instead of in the class?!F
of the calling object.
- fixed: RT #14959: problem with wrap_children when
an attribute of one of the child element includes
a '>'
- improved: the docs for wrap_children
- added: a better error message when re-using an
existing twig during the parse
- fixed: (partially) a bug with windows line-endings in
CDATA sections with keep_encoding set (RT #14815)
- added: Test::Pod::Coverage test to please the kwalitee
police ;--)
3.21 - 2005-08-12
- fixed: a test that failed if Tie::IxHash was not
available
- added: link to Atom feed for the CPAN testers
results at http://xmltwig.com/rss/twig_testers.rss
3.20 - 2005-08-11
- fixed: the pod (which caused the tests to fail)
3.19 - 2005-08-10
- fixed: the fix to RT # 14008, this one should be ok
restructured tests
- added: the _dump method (probably not finished)
3.18 - 2005-08-08
- added: a fix to deal with a bug in XML::Parser in the
original_string method when used in CDATA sections
longer than 1024 chars (RT # 14008) thanks to Dan
Dascalescu for spotting the bug and providing a test
case.
- added: better error diagnostics when the wrong arguments
are used in paste
- fixed: a bug in subs_text when the text of an element
included \n (RT #13665) spotted by Dan Dascalescu
- improved: cleaned up the behaviour of erase when the element
being erased has extra_data (comments or pis) attached
- fixed: a bug in subs_text that sometimes messed up text
after the matching text
- fixed: the erase/group_tags option of simplify to make
it exactly similar to XML::Simple's
- fixed: a bug that caused XML::Twig to crash when ignore
was used with twig_roots (RT #13382) spotted by Larry
Siden
- fixed: bug in xml_split with default entities (they
ended up being doubly escaped)
- fixed: various bugs when dealing with ids (changing
existing ids, setting the attribute directly...)
- improved mark and split, both methods now accepts several
tags/ as arguments, so you can write for example:
$elt->mark( qr/^(\w+): (.*)$/, 'dt', 'dd');
- added: XML::Twig::Elt children_trimmed_text method,
patch sent by ambrus (RT #12510)
- changed: children_text and children_trimmed_text to
have them return the entire text in scalar context
- fixed: bug that caused XML::Twig not to play nice with
XML::Xerces (due to improper import of UNIVERSAL::isa)
spotted and patched by Colin Robertson.
- changed: most references to 'gi' in the docs, replaced
them by tag. I guess Robin Berjon's relentless teasing
is to be credited with this one.
- added: tag_regexp condition on handlers (a regexp instead
of a regular condition will trigger the handler if the
tag matches), suggested by Franck Porcher, implementation
helped by a few Perl Monks
(http://perlmonks.org/index.pl?node_id=445677).
- fixed: typos in xml_split (RT #11911 and #11911),
reported by Alexey Tourbin
- added: tests for xml_split and xml_merge and fixed
a few bugs in the process
- added: the -i option to xml_split and xml_merge,
that use XInclude instead of PIs (preliminary
support, the XInclude namespace is not declared
for example).
- added the XML::Twig and XML::Twig::Elt trim method
that trims an element in-place
-added the XML::Twig last_elt method and the XML::Twig::Elt
last_descendant method
- added: more tests
3.17 - 2005-03-16
- improved: documentation, mostly to point better to
the resources at http://www.xmltwig.com
-fixed: a few tests that would fail under perl 5.6.*
and Solaris (t/test_safe_encode.t and t/test_bug_3.15.t),
see RT bug # 11844, thanks to Sven Neuhaus
- changed: the licensing terms in the README to match the
ones in the main module (same as Perl), see RT bug #11725
- added: a test on XML::SAX::Writer version number to
avoid failing tests with old versions (<0.39)
- improved: xml_split
3.16 - 2005-02-11
- added: the xml_split/xml_merge tools
- fixed: PI handler behaviour when used in twig_roots mode
- fixed: bug that prevented the DTD to be output
when update_DTD mode is on, no DTD is present but
entities have been created
- added: level(<n>) trigger for handlers
- fixed: bug that prevented the output_filter to be
called when printing an element. Spotted thanks to
Louis Strous.
- fixed: bug in the nsgmls pretty printer that output
invalid XML (an extra \n was added in the end tag)
found by Lee Goddard
- fixed: test 284 in test_additional to make it pass
in RedHat's version of perl 5.8.0, thanks to
rdhayes for debugging and fixing that test.
- improved: first shot at getting Pis and comments back in the
proper place, even in 'keep' mode. At the moment
using set_pcdata (or set_cdata) removes all
embedded comments/pis
- fixed: a bug with pi's in keep mode (pi's would not
be copied if they were within an element) found by
Pascal Sternis
- added: a fix to get rid of spurious warnings, sent
by Anthony Persaud
- added: the remove_cdata option to the XML::Twig new
method, that will output CDATA sections as regular
(escaped) PCDATA
- added: the index option to the XML::Twig new method,
and the associated XML::Twig index method, which
generates a list of element matching a condition
during parsing
- added: the XML::Twig::Elt first_descendant method
- fixed: bug with the keep_encoding option where
attributes were not parsed when the element name was
followed by more than one space (spotted by Gerald
Sedrati-Dinet),
see https://rt.cpan.org/Ticket/Display.html?id=8137
- fixed: a bug where whitespace at the begining of an
element could be dropped (if followed by an element
before any other character). Now whitespace is
dropped only if it includes a \n
- added: feature: when load_DTD is used, default
attributes are now filled
- fixed: bug on xmlns in path expression trigger
(would not replace prefixes in path expressions),
spotted by amonroy on perlmonks, see
http://perlmonks.org/index.pl?node_id=386764
- optimized: XML::Twig text, thanks to Nick Lassonde
for the patch
- fixed: bug that generated an empty line before some
comments (pointed out by Tanya Huang)
- fixed: tests to check XML::Filter::BufferText version
(1.00 has a bug in the CDATA handling that makes XML::Twig
tests fail).
- added: new options --nowrap and --exclude (-v) to xml_grep
- fixed: warning in tests under 5.8.0 (spotted by Ed Avis)
- improved: skipped HTML::Entities tests in 5.8.0 (make test for this
module seem to fail on my system, it might be the same
elsewhere)
- fixed: bug RT #6067 (problems with non-standard versions of
Scalar::Utils which do not include weaken)
- fixed: bug RT #6092 (error when using safe output filter)
- fixed: bug when using map_xmlns, tags in default namespace
were not output
3.15 - 2004-04-05
- fixed: tests now pass on more systems (thanks to Ed Avis for his testing)
- added: normalize_space option for simplify (suggestion of Lambert Lum)
- improved: removed usage of $&
- improved: the doc for paste, as it was a bit short (suggestion of Richard Jolly)
3.14 - 2004-03-17
- improved: namespace processing , it should work fine now,
as long as twig_roots is not used.
- COMPATIBILITY WARNING:
Potentially uncompatible change: the behaviour of simplify has
been changed to mimic as exactly as possible XML::Simple's XMLin
- improved: the pod to cover the entire API
- improved: tests, now pass with perl 5.005_04-RC1 (fail with 5.005 reported
by David Claughton), added more tests and a config summary at the
end of the tests
- added: methods on the class attribute, convenient for dealing with
XHTML or preparing display with CSS:
class set_class add_to_class att_to_class add_att_to_class
move_att_to_class tag_to_class add_tag_to_class set_tag_class in_class
navigation functions can use '.<class>' expressions
- fixed: (yet another!) bug in the way DTDs were output
- fixed: bug for pi => 'drop' option
- changed: the names of lots on internal (undocumented) methods, prefixed
them with _
3.13 - 2004-03-16 - maintenance release to get the tests to pass on various platforms
- improved: the README file
- fixed: problem with encoding conversions (using safe_encode and
safe_encode_hex) under perl 5.8.0, see RT ticket #5111
- fixed: tests to pass when trying to use an unsupported iconv filter
3.12 - 2004-01-29 - new features and greatly increased test coverage
- added: lots of tests (>900), thanks to David Rigaudiere, Forrest
Cahoon, Sebastien Aperghis-Tramoni, Henrik Tougaard and Sam Tregar
for testing this release on various OSs, Perl, XML::Parser and
expat versions.
- added: XML::Twig::XPath that uses XML::XPath as the XPath engine
for findnodes, findnodes_as_string, findvalue, exists, find and
matches. Just use XML::Twig::XPath instead of use XML::Twig;
(see the tests in t/xmlxpath_*).
- added: special case to output some HTML tags ('script' to start with)
as not empty.
- fixed: XML::Twig::Elt->new now properly flags empty elements (spotted by
Dave Roe)
- added: XML::Twig::Elt contains_a_single method
- added: #ENT twig_handlers (not necessarily complete, so not yet
documented, needs more tests)
- added: doc for XML::Twig and XML::Twig::Elt subs_text methods
tags starting with # are now "invisible" (they are not output),
useful for example for pretty_printing
- added: new options --wrap '' and --date to xml_grep
improved XPath support (added [nb] support)
- added: xpath method, which generates a unique XPath for an element
- added: has_child and has_children as synonyms of first_child
- added: XML::Twig::set_id_seed to control how generated id's are
created
- improved: when using ignore on an element, end_tag_handlers are now tested
at the end of the element (so you can for exemple get the byte
offset in the document), suggestion of Philippe Verdret
- added: XML::Twig::Elt change_att_name
- fixed: XML::Twig::Elt new now properly works when called as an object
(and not a class) method
- fixed: namespace processing somewhat
- fixed: SAX output methods
- fixed: bug when keep_atts_order on and using set_att on an element
with no existing attribute (spotted by scharloi)
- COMPATIBILITY WARNING:
WARNING - potentially incompatible changes -
when using finish_print, the document used to be flushed. This is no
longer the case, you will have to do it before calling finish_print.
This way you have the choice of doing it or not.
- improved: removed XML::Twig::Elt::unescape function (was no longer used)
3.11 - 2003-08-28
- added: --text_only option to xml_grep (outputs the text of the
result, without tags)
- fixed: bug where "Comments [was] always dropped after a twig
object set 'comments' to 'drop'" (RT#3711), bug report and first
patch by Simon Flack
- added: option "keep_atts_order" that keeps the
original attribute order in the output. This option needs the
Tie::IxHash module to work.
3.10 - 2003-06-09
- added: xml_pp xml_grep and xml_spellcheck to the distribution
- improved: the print method now calls 'print $elt->sprint' instead of printing
content as it converts them to text, in order to reduce the number
of calls to Perl's print (which should increase performance)
- changed: XML::Twig::Elt erase to allow erasing the root element
if it has only 1 child
- added: findvalue method to XML::Twig and XML::Twig::Elt
- added: aliased findnodes to get_xpath in XML::Twig and XML::Twig::Elt

now return the element for easier chains
- fixed: bug in pretty printing comments before elements (RT #2315)
- added: the XML::Twig::Elt children_copy method which returns a list
of elements that are copies of the children of the element
- fixed: a bug in wrap_in when the element wrapped is not attached to a tree
- fixed: bug with get_xpath: regexp modifiers were not taken into account
spotted by Eric Safern (RT #2284)
- fixed: bug in methods inherited from XML::Parser::Expat (arguments
were not properly passed)
- improved: installed local empty SIG handlers to trap error messages triggered
by require for optional modules, so that user signal handlers would
not have to deal with them (suggestion from Philippe Verdret)
- fixed: bug in the navigation XPath engine: text() was used instead of
string(). Both are now allowed.
- added: XML::Twig::Elt sort_children, sort_children_on_value,
sort_children_on_att and sort_children_on_field methods that sort the
children of an element in place
- added:XML::Twig::Elt field_to_att and att_to_field methods
- fixed:a memory leak due to ids not being weak references
- added: the XML::Twig::Elt wrap_children method that wraps children
of an element that satisfy a regexp in a new element
- added: the XML::Twig::Elt add_id method that adds an id to an element
- added: the XML::Twig::Elt strip_add method that deletes an attribute
from an element and its descendants
- COMPATIBILITY WARNING
fixed:a quasi-bug in set_att where the hash passed in reference was
used directly, which makes it a problem when the same reference is
passed several times: all the elements share the same attributes.
This is a potentially incompatible change for code that relied on
this feature. Please report problems to the author.
- fixed: bug in set_id
- fixed: bug spotted by Bill Gunter: allowed _ as the initial character
for XML names. Also now allow ':' as the first element
- added: the simplify methods, which load a twig into an XML::Simple like
data structure

- improved: the README (fleshed out examples, added OS X to the list of
tested platforms)
- fixed: bug when using the no_dtd_output option
- added: doc for the XML::Twig::Elt children_count method
- added: the XML::Twig::Elt children_text method
- improved: updated the doc so it can be properly formated by my custom pod2html,
the generated doc (with a bigger ToC and better links) is available
from the XML::Twig page at http://xmltwig.com/xmltwig/
3.09 - 2002-11-10
- added: XML::Twig::Elt xml_text method
- fixed: several bugs in the split method under 5.8.0 when matching a utf8
character (thanks to Dominic Mitchell who spotted them)
- improved: cleaned-up the pod (still in progress)

an element in its parent's child list
- fixed: re-introduced parseurl (thanks to Denis Kolokol for spotting its
absence in this version)
- fixed: ent_tag_handlers were not called on the root (thanks
to Philippe Verdret
- improved: #PI (also declared as '?') and #COMMENT handler support
- added: check on reference type (must be XML::Twig::Elt) in
XML::Twig::Elt::paste (patch by Forrest Cahoon)
3.08 - 2002-09-17
- fixed: the previous fix wasn't enough :--(
3.07 - 2002-09-17
- fixed:the way weaken is imported from Scalar::Util
3.06 - 2002-09-17
- added: XML::Twig::Elt trimmed_text and related methods (trimmed_field,
first_child_trimmed_text, last_child_trimmed_text...)
- added: XML::Twig::Elt replace_with method
- added: XML::Twig::Elt cut_children method
- added: XML::Twig contains_only method
- added: *[att=~ /regexp/] condition type (suggested by Nikola Janceski)
- fixed: bug in the way handlers for gi, path and subpath were chained
(Thanks to Tommy Wareing)
- fixed: bug where entities caused an error on other handlers (Thanks
to Tommy Wareing)
- fixed: bug with string(sub_elt)=~ /regexp/ (thanks to Tommy Wareing)
- fixed: bug with output_filter used with expand_external_entities
(thanks to Tommy Wareing)
- fixed: (yet another!) bug with whitespace handling (whitespace, then an
entity made the whitespace move after the entity) (spotted by the usual
Tommy Wareing)
- added: an error message when pasting on an undef reference (suggestion
of Tommy Wareing)
- fixed: bug in in_context (found by Tommy Wareing)
- fixed: bug when loading the DTD (local undef $/ did not stay local,
bug found and patch sent by Steve Pomeroy and Henry Cipolla)
- fixed: bug in setting output filter
- fixed: bug in using a filehandle with twig_print_outside_roots
- added: safe_encode_hex filter
- fixed: bug in set_indent, $INDENT not set properly (thanks
to Eric Jain)
- fixed: dependencies (no check with 5.8.0, added Scalar::Util
as a possible source for weaken)
- added: no_prolog option to XML:Twig::new
- improved: tested build on Windows (thanks to Cory Trese and Josh Hawkins)
- changed:in 3.05
- added: _ALPHA_ SAX export methods:
XML::Twig toSAX1, toSAX2, flush_toSAX1, flush_toSAX2 XML::Twig::Elt toSAX1, toSAX2
The following gotchas apply:
+ these methods work only for documents that are completely
loaded by XML::Twig (ie if you use twig_roots the data
outside of the roots will not be output as SAX).
+ SAX1 support is a bit dodgy: the encoding is not preserved
(it is always set to 'UTF-8'),
+ locator is not supported (and probably will not, what's the
location of a newly created element?)
Also when exporting SAX you should consider setting Twig to a
mode where all aspects of the XML are treated as nodes by XML::Twig,
by setting the following options when you create the twig:
comments => 'process', pi => 'process', keep_spaces => 1
- improved: twig_print_outside_roots now supports a file handle ref as argument:
the untouched part of the tree will be output to the filehandle:
- added: the 'indented_c' style that gives a slightly more compact pretty
print than 'indented': the end tags are on the same line as the
preceeding text (suggestion of Hugh Myers)
- added: option in get_xpath (aka find_nodes) to apply the query to
a list of elements
- added: processing of conditions on the current node in get_xpath:
my @result= get_xpath( q{.[@att="val"]});
This is of course mostly useful with the previous option.
The idea stemmed from a post from Liam Quin to the perl-xml list
- added: XML::Twig xml_version, set_xml_version, standalone, set_standalone
methods on the XML declaration
- fixed: bug in change_gi (which simply did not work at all), found
by Ron Hayden.
- fixed: bug in space handling with CDATA (spaces before the CDATA section
were moved to within the section), comments and PI's
- fixed: bug in parse_url (exit was not called at the end of the child),
found by David Kulp
- improved: cleanup a bit the code that parses xpath expressions (still some work
to be done on this though), fixed a bug with last, found by Roel de Cock
- fixed: the SYNOPSIS (parsefile is used to parse files, spotted by e.sammer)
- fixed: bug in pretty printing (reported by Zhu Zhou)
- fixed: bugin the install: the Makefile now uses the same perl used
to perl Makefile.PL to run speedup and check_optional_modules
(reported by Ralf Santos)
- fixed: bugs in pretty printing when using flush, trying to figure out
as well as possible if an element contains other elements or text
(there is still a gotcha, see the BUGS section in the docs)
- fixed: bug that caused the XML declaration and the DTD not to be reset
between parses
- improved: the conversion functions (errors are now reported when the
function is created and not when it is first used)
- added: the output_encoding option to XML::Twig->new, which allows
specifying an encoding for the output: the conversion filter is
created using Encode (perl 5.8.0) Text::Iconv or Unicode::* The
XML declaration is also updated
- added: #CDATA and #ENT can now be used in handler expressions
- added: XML::Twig::Elt remove_cdata method, which turns CDATA sections
into regular PCDATA elements
- improved: set_asis can now be used to output CDATA sections un-escaped (and without
the CDATA section markers)
3.04 - 2002-04-01
- fixed: handlers for XML::Parser 2.27 so the module can pass the tests
3.03 - 2002-03-26
- fixed: bugs in entity handling in twig_roots mode
- added: the ignore_elts option, to skip completely elements
- improved: enhanced the XPath-like syntax in navigation and get_xpath
methods: added operators (>, < ...)
- fixed: [RT 168]: setTwigHandler failed when no handler was already set
(thanks to Jerry)
- improved: turned %valid_option into a package global so AnyData can access it
- fixed: bug in sprint that prevented it from working with filters
- fixed: bug in erase when erasing an empty element that was the
last child of its parent ([RT390], thanks to Julian Arnold)
- fixed: copy now correctly copies the asis status of elements
- fixed:typos on the docs (thanks to Shlomo Yona)
- added: tests (for erase and entities in twig_roots mode)
3.02 - 2002-01-16
- fixed: tweaked speedup to replace constructs that did not work in
perl 5.005003
3.01 - 2002-01-09
- fixed: the directory name in the tar file
3.00 - 2002-01-09
- COMPATIBILITY
WARNING: THIS CHANGE IS NOT BACKWARD COMPATIBLE
But it is The Right Thing To Do
In normal mode (when KeepEncoding is not used) the XML data is
now stored as parsed by XML::Parser, ie the base entities are
expanded. The "print" methods (print, sprint and flush, plus the
new xml_string, pcdata_xml_string and att_xml_string) return the
data in XML-escaped form: & and < are escaped in PCDATA and
&, < and the quote (" by default) are turned to & < and
" (or ' if the quote is '). The "text" methods (text,
att and pcdata) return the stored text as is.
So if you want to output XML you should use the "print" methods
and if you want to output text you should use the "text" methods.
Note that this breaks the trick consisting in adding tags to the
content of an element: $elt->prefix( "<b>") no longer adds a <b>
tag before an element. $elt->print will now output "<b>...".
(but you can still use it by marking those elements as 'asis').
It also fixes the annoying ' thingie that used to replace '
in the data.
When the KeepEncoding option is used this is not true, the data
is stored asis, base entities are kept un-escaped.
Note that KeepEncoding is a global setting, if you use several twigs,
some with KeepEncoding and some without then you will have to manually
set the option using the set_keep_encoding method, otherwise the last
XML::Twig::new call will have set it
In addition when the KeepEncoding option is used the start tag is
parsed using a custom function parse_start_tag, which works only
for 1-byte encodings (it is regexp-based). This method can be
overridden using the ParseStartTag (or parse_start_tag) option
when creating the twig. This function takes the original string as
input and returns the gi and the attributes (in a hash).
If you write a function that works for multi-byte encodings I would
very much appreciate if you could send it back to me so I can add it
to the module, so other users can benefit from it.
An additional option ExpansExternalEnts will expand external entity
references to their text (in the output, the text stored is &ent;).
- added: when handlers (twig_handlers or start_tag_handlers) are called
$_ is set to the element node, so quick hacks look better:
my $t= new XML::Twig( twig_handlers =>
{ elt => sub { print $_->att( 'id'), ": ", $_->text, "\n"; } }
);
- added: XML::Twig dispose method which properly reclaims all the memory
used by the object (useful if you don't have WeakRef installed)
- added: XML::Twig and XML::Twig::Elt ignore methods, which can be called
from a start_tag_handlers handler and cause the element (or the
current element if called on a twig) to be ignored by the
parsing
- added: XML::Twig parse_start_tag option that overrides the default function
used to parse start tags when KeepEncoding is used
- added: XML::Twig::Elt xml_string, pcdata_xml_string and att_xml_string
all return an XML-escaped string for an element (including
sub-elements and their tags but not the enclosing tags for the
element), a #PCDATA element and an attribute
- added: XML::Twig::Elt methods tag and set_tag, equivalent respectively
to gi and set_gi
- added: XML::Twig and XML::Twig::Elt set_keep_encoding methods can be used
to set the keep_encoding value if you use several twigs with
different keep_encoding options
- improved: option names for XML::Twig::new are now checked (a warning is output
if the option is not a valid one);
- improved: when using pretty_print nice or indented keep_spaces_in is now checked
so the elements within an element listed in keep_spaces_in are not
indented
- added: XML::Twig::Elt insert_new_elt method that does a new and a paste
- added: XML::Twig::Elt split_at method splits a #PCDATA element in 2
- added: XML::Twig::Elt split method splits all the text descendants of an
element, on a regep, wrapping text captured in brackets in the
regexp in a specified element, all elements are returned
- added: XML::Twig::Elt mark method is similar to the split method, except
that only newly created elements (matched by the regexp) are
returned
- added: XML::Twig::Elt get_type method returns #ELT for elements and the gi
(#PCDATA, #CDATA...) otherwise
- added: XML::Twig::Elt is_elt returns the gi if the element is a real element
and 0 if it is #PCDATA, #CDATA...
- added: XML::Twig::Elt contains_only_text returns 1 if the element contains no
"real" element (is_field is another name for it)
- added: First implementation of the output_filter option which filters the
text before it is output by the print, sprint, flush and text methods
(only works for print at the moment, and still under test with various
versions of XML::Parser). Standard filters are also available
Example:
#!/bin/perl -w
use strict;
use XML::Twig;
my $t = new XML::Twig(output_filter => 'latin1');
$t->parse( \*DATA);
$t->print;
__DATA__
<?xml version="1.0" encoding="ISO-8859-1"?>
<docù atté="valuè">Un homme soupçonné d'être impliqué dans
la mort d'un motard de la police, renversé
</docù>
The 'latin1', 'html' and 'safe' filters are predefined, you can also
build additional filters using Iconv (requires text::Iconv) and
Unicode::String (requires Unicode::String and Unicode::Map8):
my $conv = XML::Twig::iconv_convert( 'latin1');
my $t = new XML::Twig(output_filter => $conv);
my $conv = XML::Twig::unicode_convert( 'latin1');
my $t = new XML::Twig(output_filter => $conv);
warning: conversions work fine with XML::Parser 2.27 but sometimes fail
with XML::Parser 2.30 (on Perl 5.6.1, Linux 2.4 on a PC) when using
'latin1' without Text::Iconv or Unicode::String and Unicode::Map8
installed.
The input_filter option works the same way, except the text is
converted before it is stored in the twig (so you can use regexp in
your native encoding for example)
- added: the XML::Twig::Elt set_asis method sets a property of an element that
causes it to be output asis (without XML-escaping < " and &) so you
can still create tagged text
- added: the XML::Twig::Elt prefix and suffix methods accept an optional
'asis' argument that causes the prefix or suffix to get the asis
property (so you can do $elt->prefix( '<b>foo</b>', 'asis') for
example)
- added: the XML::Twig and XML::Twig::Elt find_nodes methods are aliases
to the get_xpath method (this is the name used in XML::XPath)
- added: the XML::Twig parseurl and safe_parseurl methods parse a document
whose url is given
- added: XML::Twig::Elt extra_data, set_extra_data and append_extra_data to
access the... extra data (PI's and comments) attached to an element
- added: XML::Twig method parser returns the XML::Parser::Expat object used
by the twig
- improved: Most XML::Parser::Expat methods are now inherited by XML::Twig
objects
- added: XML::Twig::Elt descendant_or_self method that returns the element
and its descendants
- fixed: element (and attribute) names can now include '.'
- fixed: get_xpath now works for root based XPath expressions ('/doc/elt')
- fixed: get_xpath now works for regexps (including regexps on attribute values)
- fixed: you can now properly restore pretty_print and empty_tag_style values
- fixed: speedup (at install) now checks the Perl version and uses qr or ""
so XML::Twig works in 5.004
- fixed: XML::Twig::Elt wrap_in now allows wrapping the root element
- fixed: various bugs in the DOCTYPE and DTD output with XML::Parser 2.30
- fixed: the tests to fix a bug when working with XML::Parser 2.27
- fixed: the tests to fix a bug preventing test2 to pass under windows
- fixed: _default_ handlers now work (thanks Zoogie)
- fixed: the text method now returns the XML base entities (<>&'") un-escaped
(thanks to Hakan Kallberg's persistence to ask for it ;--)
- fixed: pretty_print works better for elements without content
- fixed: end_tag_handlers now work properly (thanks to Phil Glanville for the
patch).
- improved: attributes which name starts with # are not output by the print
methods, and thus can be used to store private data on elements
- improved: WeakRef is used if installed, so no more memory leaks
- improved: sped-up print and flush by creating the _print and _flush methods
which do not check for file handle and pretty print options
- improved: the doc has been enhanced and somewhat restructured. All options are
now written as this_is_an_option although the legacy form thisIsAnOption
can still be used. Links now display properly in the text form (thanks to
Dominic Mitchell for spotting this and sending a patch)
- improved: navigation functions (including descendants) now allow not only a gi
to be used as filter, but also the '#ELT' token, to filter only "real"
elements (as opposed to #PCDATA, #CDATA, #PI, #COMMENT, #ENT), the
'#TEXT' token, to filter only text (PCDATA and CDATA elements),
regular expressions (built with qr//) applied on the elements gi's,
code references, the code is passed the element as argument, and a
subset of XPath.
Functions that can use this token are: children, first_child, last_child,
prev_sibling, last_sibling, next_elt, last_elt, descendants, get_xpath,
child, sibling, sibling_text, prev_siblings, next_siblings field,
first_child_text
- improved: the paste method now accepts a 'within' position, which inserts the
element at the $offset argument (a 3rd, required, argument) in the
reference element or in its first text child
- improved: the XML::Twig::Elt insert method now accepts attributes (hashrefs)
applied to the element(s) being inserted:
$elt->insert( e1 => { a => 'v'}, e2 => e3 => { a1 =>'v1', a2 => 'v2'});
- improved: the XML::Twig::erase method now outputs a meaningful error message if
applied to the root (or a cut element)
- improved: optimizations for better performances (in the end performances are about
the same or a little worse than XML::Twig 2.02 but the module is much
more powerful)
[Known bugs]
- the DTD interface is completely broken, and I have little hope of
fixing it considering I have to deal with 2 incompatible versions of
XML::Parser. Plus no one seems to be using it...
- some XPath/Navigation expressions using " or ' in the text()="" part
of the expression will cause a fatal error
- note that this version works better (but doesn't necessarily require)
with WeakRef (Perl version 5.6.0 and above) and Text::Iconv for all
its encoding conversions.
