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

       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".

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

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