I want to use Python to make a configuration file generator. My roughly idea is feeding input with template files and some XML files with the real settings. Then use the program to generate the real configuration files.

I got several questions:

• Is there any open source configuration generator program? (what could be the keyword), I wonder if there's anything can be added/modified in the design.

• Does Python have good XML parser module?

• Is it good idea to use XML file to save the original settings? I've been thinking to use Excel since it's more intuitive to maintain, but harder for program to parse. Not sure how people deal with this.

Hope the community can give me some suggestions. Thanks a lot!
