I have heard a good things about XMLPullParser, but I have never
tried to use it in anger.

I am not sure how the plain ElementTree (and I suppose you mean
its `findall()` method) could help me here. My main focus is on
the SAX `characters()` method, and here ElementTree with its
`.text` and `.tail` attributes doesn’t help much, although if
there was `findalltext()` method, it could get interesting.

Certainly, I am a big fan of writing just in the confines of the
Python standard library.

I know ElementTree and it is very useful for simple searches
in the XML tree, but I am not sure how it would help with this
project or with my CzeCSP conversion.

Blessings,
