I have a brain-block when it comes to Regex and really need to learn it. Can anybody suggest really good tutorials with little exercises to reinforce the info? I've tried so many times to get a grasp and it just escapes me and would be invaluable for school/work since I'm doing a lot of string processing in Perl and PHP. Thanks!
