VERSION

Version 0.2.1

SYNOPSIS

package XML::Grammar::MyGrammar::ToOtherStuff;

use MooX 'late';

use XML::GrammarBase::Role::RelaxNG;
use XML::GrammarBase::Role::XSLT;

with ('XML::GrammarBase::Role::RelaxNG');
with XSLT(output_format => 'html');
with XSLT(output_format => 'docbook');

has '+module_base' => (default => 'XML-Grammar-MyGrammar');
has '+rng_schema_basename' => (default => 'my-grammar.rng');

has '+to_html_xslt_transform_basename' => (default => 'mygrammar-xml-to-html.xslt');
has '+to_docbook_xslt_transform_basename' => (default => 'mygrammar-xml-to-docbook.xslt');

package main;

my $xslt = XML::Grammar::MyGrammar::ToOtherStuff->new(
    data_dir => "/path/to/data-dir",
);

# Throws an exception on failure.
my $as_html = $xslt->perform_xslt_translation(
    {
        output_format => 'html'
        source => {file => $input_filename, },
        output => "string",
    }
);

PARAMATERS

output_format

A Perl identifier string identifying the format.

SLOTS

module_base

The basename of the module - used for dist dir.

data_dir

The data directory where the XML assets can be found (the RELAX NG schema, etc.)

rng_schema_basename

The Relax NG Schema basename.

to_${output_format}_xslt_transform_basename

The basename of the primary XSLT transform file. Should be overrided in the constructor or using has '+to_html'. For example:

has '+to_html_xslt_transform_basename' => (default => 'fiction-xml-to-html.xslt');

METHODS

$self->rng_validate_dom($source_dom)

Validates the DOM ( $source_dom ) using the RELAX-NG schema.

$self->rng_validate_file($file_path)

Validates the file in $file_path using the RELAX-NG schema.

$self->rng_validate_string($xml_string)

Validates the XML in the $xml_string using the RELAX-NG schema.

$converter->perform_xslt_translation

  • my $final_source = $converter->perform_xslt_translation({output_format => $format, source => {file => $filename}, output => "string" })

  • my $final_source = $converter->perform_xslt_translation({output_format => $format, source => {string_ref => \$buffer}, output => "string" })

  • my $final_dom = $converter->perform_xslt_translation({output_format => $format, source => {file => $filename}, output => "dom" })

  • my $final_dom = $converter->perform_xslt_translation({output_format => $format, source => {dom => $libxml_dom}, output => "dom" })

  • my $final_dom = $converter->perform_xslt_translation({output_format => $format, source => {dom => $libxml_dom}, output => {file => $path_to_file,}, })

  • my $final_dom = $converter->perform_xslt_translation({output_format => $format, source => {dom => $libxml_dom}, output => {fh => $filehandle,}, })

This method does the actual conversion with the output format of $format. The 'source' argument points to a hash-ref with keys and values for the source. If 'file' is specified there it points to the filename to translate (currently the only available source). If 'string_ref' is specified it points to a reference to a string, with the contents of the source XML. If 'dom' is specified then it points to an XML DOM as parsed or constructed by XML::LibXML.

The 'output' key specifies the return value. A value of 'string' returns the XML as a string, and a value of 'dom' returns the XML as an XML::LibXML DOM object. If it is a hash ref then it specifies a 'file' or a 'fh' with a filepath or filehandle respectively.

An optional 'encoding' parameter determines if one should output the string as 'utf8' (the deafult - using XML::LibXSLT's output_as_chars()) or as 'bytes' - using its output_as_bytes() .

An optional 'xslt_params' parmater allows one to specify a hash of XSLT parameters.

BUILD

THANKS

Thanks to Matt S. Trout http://metacpan.org/author/MSTROUT and other people from #moose on irc.perl.org for helping me figure out Moo / MooX and steer me away from Any::Moose , and for writing the Moo ecosystem.
