NAME

       Catmandu::XML::Transformer - Utility module for XML/XSLT processing

SYNOPISIS

           $transformer = Catamandu::XML::Transformer->new( stylesheet => 'file.xsl' );

           $xml_string = $transformer->transform( $xml_string ); # SCALAR
           $xml_dom    = $transformer->transform( $xml_dom );    # XML::LibXML::Document
           $xml_struct = $transformer->transform( $xml_struct ); # ARRAY reference
           $xml_simple = $transformer->transform( $xml_simple ); # HASH reference

           $transformer = Catamandu::XML::Transformer->new( output_format => 'string' );
           $xml_string  = $transformer->transform( $xml );       # any XML to SCALAR

CONFIGURATION

       stylesheet
           Zero or more XSLT files given as comma-separated list of files or array reference with
           multiple files to apply as transformation pipeline. Files are parsed once on
           instantiation of the Catmandu::XML::Transformer object.

       output_format
           Expected output format "dom", "string", "struct", "simple". By default the input
           format triggers the output format. If the last stylesheet has text output
           ("<xsl:output method="text"/>") then output format is automatically set to "string".

METHODS

       stylesheet()
           Returns an array reference of XSLT filenames used as transformation pipeline.

       output_format()
           Returns the output format or "undef".
