I work with the author of XML::Simple .. and he would (and does) tell people not to use it for anything than parsing very simple XML structures. http://search.cpan.org/~grantm/XML-Simple-2.18/lib/XML/Simple.pm#WHERE_TO_FROM_HERE? So do I understand from what you are saying, that Galens work is not useful, and that a pureperl XML parser is the only way forward? I hope this is just another language based misunderstanding. Because I disagree totally if not.
