I don't know of a better page for Perl XML info, but I can offer a bit of
info on XML::XPath and the suggested replacement.

XML::XPath is a pure-Perl implementation.  I usually grab it for quick and
dirty stuff because it's easily fast enough for my needs, and doesn't
require external dependencies.  If you want something similar that is more
actively maintained, I'd suggest looking at XML::LibXML.  It uses the GNOME
libxml library to do the heavy lifting, and it also provides a similar xpath
interface.  In my experience, for small XML::XPath projects, porting form
XML::XPath to XML::LibXML probably wouldn't take much effort[0].  Matt
Seargent, the guy behind XML::XPath, was also the (or one of the) initial
guys behind XML::LibXML, so the xpath part looks pretty similar between
them.

Most distributions have packages for XML::LibXML, but if you're
pulling/building it from cpan, you'll need both libxml and its dev/devel
package with headers and such.

totaled less than 200 lines, and the XML related stuff was only a few dozen
lines or so of the code.
