Python or Perl regex's are not actually regular expressions. Real regular expression compilers produce blazing fast results, but they cannot support many of the features of offered by the search-and- backtrack engines that Python and Perl use. > For speed, consider hand-coding your own state > machine. Preferably in a compiled language like C. The speed of a real regular expression engine is hard to beat. I assume you're not actually suggesting hand-writing a state machine for the problem at issue here, which requires recognizing about 5000 different words. -- --Bryan -- http://mail.python.org/mailman/listinfo/python-list
