[CentOS] python XML processing to turn a XML file into a structure?

Hi,

 I'm running Centos 5 with python 2.4.3. Anyone know
if there are python xml processing tools/packages that
can turn an XML file directly into a complex
structure? and write a complex structure back into an
XML file?

I'm a newbie to Python programming, though years ago
I've processed XML files with Java but now I am in a
rush. 

Thanks.
