Regex Stop Match Before Character

[Ptrick125 45]

I am working on a url scraper, and the website tends to include the referall source, but I cannot include that when saving it to a file later on. I was successful in getting it to grab everything after the "/".
 
testwebsite.com/ubotstudio?ref=referral 
 
This is what I have so far:
 
[^/]*$
testwebsite.com/ubotstudio?ref=referral
 
How should I have it match everything before the "?" sign?

The simplest way to do it is this:

 

.*(?=\?)

 

But it would be nice to know if the format will always be like that so you can come up with something better. For example if the format is always like that (url without www or http) then you can also use something more specific:

 

[a-zA-Z0-9]+\.[a-zA-Z]{2,4}[a-zA-Z0-9\/\.-_+%!]+(?=\?)
