ElementTree is a good candidate for processing xml:  
http://effbot.org/zone/element.htm
It provides a "natural" way to access elements and attributes, instead of  
writing the same handler again and again or using slow DOM functions of  
gigantic names.

Pickle is good for storing data that will be loaded again by (the same, or  
another) Python program. The format isn't portable to other languages, it  
isn't readable, may have security issues. But it's extensible and much  
more flexible than the other builtin alternative, marshal. You can use  
pickle as a serializer if you're aware of its limitations.
