I need the encoding information, because later I need to convert
unicode back to that coding. Unfortunately I can't change the XML
format while it's not in my hands (I can't put into another element).

Yes, this was the 1st thing I tryed out. Unfortunately I got:
Traceback (most recent call last):
File "./xmlparser_new.py", line 210, in ?
AttributeError: ExpatParser instance has no attribute 'parseString'
Do you have an idea how to fix it? (yes, I underestand that it's not
supported by expat - unfortunately I don't have experience with it).
python-2.3.3, Debian Woody, libexpat1-1.95.2-6, libexpat1-dev-1.95.2-6
