The modified version can then be saved back out as well. 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. > 2) Is XML fairly standard for this in Python?

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. -- Gabriel Genellina -- http://mail.python.org/mailman/listinfo/python-list
