regex to match all uppercase letters before the first question mark

I am attempting to create a regex that will match all uppercase letters before the first question mark in a URL string:

/foO/baR/?_heLLo=1320957051041105000&_woRld=0

I have tried both the following:

(?<!(\?))([A-Z])
(?<!\?.*?)([A-Z])

The former captures uppercase letters before and after the question mark. The latter captures no uppercase letters. Any insight would be appreciated, thanks.

This regex would do the trick:

[A-Z](?=.*?\?)

Try this positive lookbehind:

(?<=^[^?]*)[A-Z]
