Yes, sure. Thanks, but
that's not what I wanted to know.
Perhaps I wasn't clear enough.
It's not really so much XML related...

Is there a better syntax for self.__class__.__dict__[handler]?
And where should the "output" go to?
All examples use print statements in the element handlers.
I wrote those get... methods - but I guess they don't belong in the XML
handler, but perhaps in the parser or somewhere else.
It works, but I don't think it's good design.

I should ask the last question on the twisted ML, I guess:
