The documentation does not indicate that this module is not an XML parser. It's not even a useful subset.
The interface mimicks that of XML::Parser, which is hardly one of the best interfaces out there. That makes it a lot less easy to use than pretty much anything else.
Overall, this has nothing to do in the XML::* hierarchy, if you're looking for an XML parser use something else.
This is simply one of the most excellent tools I have ever used.
Apart from the incomplete bits in XML::SAX::PurePerl, this is a rocking distro!
