You have some good answers already, but I wanted to let you know about a tool you may already have which is useful for experimenting with regexps. On windows, the file `redemo.py` is in the Tools/Scripts folder. If you're on a Mac, see http://stackoverflow.com/questions/1811236/how-can-i-run-redemo-py-or-equivalent-on-a-mac It has really helped me work on some tough regexps. good luck, --Tim -- https://mail.python.org/mailman/listinfo/python-list
