Mapping Python objects and XML

[Hung Jung Lu]

Hi,

If I need to map Python objects into XML structure and vice-versa, is 
there any Python class I can use as base class?

Mapping Python objects into XML probably is not too hard, if the 
objects don't contain things like object-bound methods. How about the 
reverse process? I think I can include the class tag in the XML, so 
during the re-creation process, I can call the appropriate 
constructors for the objects. I think a base Python class can be 
created to handle this kind of things, if the data fields are not too 
exotic (e.g: numbers, strings) This must be a very common need. So I 
am wondering whether this base class is already available.

(By the way: anything similar in Java?)

Thanks!
