Good.

I would prefer it if you wrote to the mailing list. Admittedly, there are not
a lot of subscribers currently, but at least your questions get archived that
way, so that others can find them on the web.

What do you need a MathML parser for? How is that more than a validating XML
parser?

(and how is that different from what MathDOM already gives you?)

As I said, look at the Python scripts that come with MathDOM. They use quite a
big part of the API, so they may give you enough hints already.

Hmm, ok, now that's using the PyXML implementation of MathDOM. I'll have to
check what's not working here. Any reason you can't keep using MathDOM with
lxml? It's the preferred way anyway.
