To second Paul's suggestion, usually, if the regex is not immediately obvious, its probably better to look into parsing modules, pyparsing being one of the most accessible modules (to me, anyways)--and well worth learning. However, in complicated applications, regex is usually still fun and valuable as an intellectual exercise.
