Thanks for this suggestion.

I've not come accress ElementTree before, but it looks really useful
(plus there are Debian packages :-)

The only thing is that I've already written quite a lot of my code using
minidom and mixing the two sounds like a recipe for disaster. But I'll
certainly keep ET in mind for my next Python/XML project!
