Constructors etc.

new
$fmt = CLASS_OR_OBJ->new(%args);

Constructor.

%args, %$fmt:

##-- input
xdoc => $xdoc,                          ##-- XML::LibXML::Document
xprs => $xprs,                          ##-- XML::LibXML parser
##
##-- output
encoding => $inputEncoding,             ##-- default: UTF-8; applies to output only!
level => $level,                        ##-- output formatting level (default=0)

#(nothing here)

Methods: Persistence

noSaveKeys
@keys = $class_or_obj->noSaveKeys();

Override: returns list of keys not to be saved. Here, qw(xdoc xprs).

Methods: Input

close
$fmt = $fmt->close();

Override: close current input source.

fromFile
$fmt = $fmt->fromFile($filename_or_handle);

Override: select input from file.

fromFh
$fmt = $fmt->fromFh($fh);

Override: select input from filehandle $fh.

fromString
$fmt = $fmt->fromString($string);

Override: select input from string $string.

Methods: Output

flush
$fmt = $fmt->flush();

Override: flush accumulated output.

toString
$str = $fmt->toString();
$str = $fmt->toString($formatLevel);

Override: flush buffered output to byte-string. $formatLevel is passed to XML::LibXML::Document::toString(), and defaults to $fmt->{level}.

toFh
$fmt_or_undef = $fmt->toFh($fh,$formatLevel);

Override: flush buffered output document to filehandle $fh.

xmlDocument
$xmldoc = $fmt->xmlDocument();

Returns output buffer $fmt->{xdoc}, creating it if not yet defined.

xmlRootNode
$rootnode = $fmt->xmlRootNode();
$rootnode = $fmt->xmlRootNode($nodname);

Returns output buffer root node, creating one if not yet defined.

$nodname is the name of the root node to create (if required); default='doc'.
