I also saw this http://www.intertwingly.net/blog/1438.html in the
Daily Python-URL that looks interesting (haven't followed up)

However, the following comment doesn't necessarily recommend to use
it:


Hmm... XML Objectify (which I contributed to), available by David
Mertz here: http://gnosis.cx/download/Gnosis_Utils-current.tar.gz
does the same thing as xmltramp, it can work off expat (scaling much
better) and allows you to override class/tag behavior in Python.
Xmltramp is a nice hack (and much prettier than Objectify, source-code
wise), but XO is way more powerful.
