I think your task is made problematic by the possibility that no single part of the regexp causes a match failure. What causes failure depends on what branches are chosen with the |, *, +, ?, etc. operators -- it might be a different character/subexpression for each branch. And then there's exponentially many possible branches. -- Devin -- http://mail.python.org/mailman/listinfo/python-list
