speed and no 3rd party tools aren't exactly compatible requirements.  however,
if it's okay for you to ship one or two python modules with your application, you
could use the ElementTree and ElementPath modules from the ElementTree kit,
together with Python's pyexpat.

by itself, ElementTree is a bit faster than most other DOM implementations.  if
you add the cElementTree module (a standard component on many modern
Linux systems), you'll end up with something that can read XML files faster
than Python can read text files:

ET is a bit limited in the XPath department, though.  if you want reasonable
speed and full XPath support (and a *lot* more), see http://codespeak.net/lxml/
