RegEx Help

[^A-Za-z0-9\._] (The ^ in there says "anything but...) Jerry Johnson >>> cftalk@becomenew.com 05/22/03 01:35PM >>> I've spent a lot of time on this and can't seem to get it right. I need a regex that says the following: Find ANY character (including spaces) other than the following characters: A-Z, a-z, 0-9, period, and underscore. The problem with the ones I've created, is the regex would find a letter and return True, because the letter wasn't a number, period, or underscore.  I need it to find a character that is not any of the charcters listed above. Anyone care to help? -Brad
