I want to accept an arbitrary regular expression from the user and anchor it on both sides in order to enforce a full match (^<user's-regex>$) however I don't know if I have to take into account the fact that the user may have already anchored his regex. It looks like Perl, C++, .NET and JavaScript all allow double multiple anchoring. ...

Hi- I'm trying to work with regexes in PHP on my school's news site (running WordPress). The idea is, whenever someone saves a post, all instances of "Regis" (without 'Jesuit' at the end) are replaced with "Regis Jesuit." (I go to Regis Jesuit High School, and they're picky about their branding). Overall this works fine with the followin...
Hi there, I am trying to write a regex that selects everything between two characters. For example, when the regex encounters a '§' I want it to select everything after the '§' sign, up until the point that the regex encounters a ';'. I tried with a lookbehind and lookahead, but they don't really do the trick. So for example " § 1-2 bl...
