A:
/^[^_]*$/
The [^] syntax means "do not include any of these characters".

That was simple. What was I thinking? Actually this was a simplification of a large regular expression problem, whose partial answer I found here - http://stackoverflow.com/questions/1240674/I guess I over simplified it while trying to isolate the problem. And couldn't find this simple answer in the mess. Anyway, thanks for enlightening.

A:
To match a character that is not an underscore you'd use [^_] (the ^ means "not"). So to match a whole string you'd do something like this:
/[^_]+/
