Document-class: LibXSLT::XSLT

The libxslt gem provides Ruby language bindings for GNOME‘s Libxslt toolkit. It is free software, released under the MIT License.

Using the bindings is straightforward:

 stylesheet_doc = XML::Document.file('stylesheet_file')
 stylesheet = XSLT::Stylesheet.new(stylesheet_doc)

 xml_doc = XML::Document.file('xml_file')
 result = stylesheet.apply(xml_doc)
