Python and XML processing with SAX

[Munna D]

Hi,
I'm trying to find a way of getting a list of all elements and attributes allowed in an XML DTD (so that I can then compare this against an XML instance and see which of the lements/attributes are not being used). Is there a way to do this with Python and SAX? I'm a comparative newbie to Python, so would be very grateful if someone could explain how I can do this with a small code example.

Thank you in advance,
Munna
