Hi Mike, You may want to look at "lookahead" assertions. These are patterns of the form '(?=...)' or '(?!...). The documentation mentions them here: http://www.python.org/doc/lib/re-syntax.html and AMK's excellent "Regular Expression HOWTO" covers how one might use them: http://www.amk.ca/python/howto/regex/regex.html#SECTION000540000000000000000 _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
