jptxs,

You will alas learn that not all XSLT engines are created equal. I've used Saxon, Xalan (both Java and C versions), MSXSLT and XML::LibXSLT, and found XPATH instructions that only one could or could not use. I've not used XML::XSLT for a while prefering the faster and I feel more feature complete XML::LibXSLT, but sometimes even this excellent parser dies, where Xalan was able to correctly transform the source.

Some additional nodes:

• Why is Perl so bad with XML?
• XML parser
• which XML module?
• perl/XML development
• XML Examples (and a call for participation)
• Perl XML FAQ

and

• XML::LibXML and XML::LibXSLT are also c based, and very fast - a particular favourite
• XML::DOM if you need a W3C DOM interface
• XML::GDOME if you need a DOM level 2 iterface
• XML::Parser if you want low level access to your XML
• XML::Sablotron another fast c based parser/XSLT engine
• XML::Simple a classic simple interface to XML in Perl
• XML::TreeBuilder a useful yet underused XML tree manipulation module
• XML::Twig another Perlish XML interface
