Re^2: Regexp match filename, exclude path

Right. I realize why the regexp I tried doesn't work. The solution can't be anything except a backslash, it has to be something like the last set of characters that isn't preceded by a backslash. I realize I could do this with a module, splitting on backslashes then taking the last element, etc., but I want to do it with a regexp if I can.

I'm not sure what you mean by The solution can't be anything except a backslash, it has to be something like the last set of characters that isn't preceded by a backslash. The following will match the last sequence of non-backslash characters in your string, which is what you seem to want: `m![^\\]+\.pdf$!;` [download] Anchoring the match makes sure you get the filename path, and the character set negation makes sure you get nothing with a backslash in it.

Anchoring the match makes sure you get the filename path, and the character set negation makes sure you get nothing with a backslash in it.
