XML::Twig

XML::Twig is an XML transformation module. It can be used to process huge documents while still being in tree mode; is not bound by DOM or SAX, so it is very Perlish and offers a very comprehensive set of methods; is simple to use; and DWIMs as much as possible. What it doesn't offer: full SAX support (it can export SAX, but only reads XML); full XPath support (unless you use XML::Twig::XPath); nor DOM support. It is also a big module, and with over 500 methods available it can be a bit overwhelming. A good starting point is the online tutorial.
