There's a DOM-walker implementation in the XML-SIG's distribution,
which you should already have if you've gotten 4DOM to work.
Look for walker.py in the dom subdirectory.

A year ago I posted some toy examples of how to use it on the XML-SIG
mailing list:

Read the whole thread, since the follow-ups on suggest important
improvements.
