You can't use lookbehind with CF's regex engine (uses Apache Jakarta ORO).

However, you can use Java's regex though, which does support them, and I've created a wrapper CFC that makes this even easier. Available from: http://www.hybridchill.com/projects/jre-utils.html

(Update: The wrapper CFC mentioned above has evolved into a full project. See cfregex.net for details.)

Also, the /.../s stuff isn't required/relevant here.

So, from your example, but with improved regex:

]+(?=>)" , "Joe " ) />

A quick note, since I've updated that regex a few times; hopefully it's at its best now...

(?<=<) # positive lookbehind - start matching at `<` but don't capture it.
[^<>]+ # any char except  `<` or `>`, the `+` meaning one-or-more greedy.
(?=>)  # positive lookahead - only succeed if there's a `>` but don't capture it.
