Match all characters except for those that start with specific characters

Question

I'm trying to figure out how to match all characters except for character array that starts with _ah :

_ah\foo
_ah\foo\bar

This is my current regex: \\b(?!\\_ah(\\w+))\\w+\\b

However this regex still matches the one listed above. What could be the problem in my regex?

Answer 1

If you are trying to match words that don't start with _ah ..

\b(?!_ah)\w+\b

This would match foo , bar
