I am a speed-maniac and crave for speed; so if the assumption is valid, i can vouch for the fact that regexp would be faster and neater solution. I have done some speed experiments in past on this (results of which i do not have handy), and i found this. XP asks you implement the best solution with the least effort and i think in this case regexp is a winner. Thoughts can vary though. _______________________________________________ BangPypers mailing list BangPypers@python.org http://mail.python.org/mailman/listinfo/bangpypers
