=head1 NAME

XML::GrammarBase::Role::XSLT - a parameterized role for XSLT conversions.

=head1 VERSION

version 0.2.6

=head1 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",
        }
    );

=head1 VERSION

version 0.2.6

=head1 PARAMATERS

=head2 output_format

A Perl identifier string identifying the format.

=head1 SLOTS

=head2 module_base

The basename of the module - used for dist dir.

=head2 data_dir

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

=head2 rng_schema_basename

The Relax NG Schema basename.

=head2 to_${output_format}_xslt_transform_basename

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

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

=head1 METHODS

=head2 $self->rng_validate_dom($source_dom)

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

=head2 $self->rng_validate_file($file_path)

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

=head2 $self->rng_validate_string($xml_string)

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

=head2 $converter->perform_xslt_translation

=back

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

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

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

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