How do I match [Any Character Except X] in a regular expression?

问题

Is there are way to do this?

So if X is the unwanted character, I'd be looking for something like (.*[^X])

The aim is to match every character in a string until an X turns up.

I've searched high and low, but can't find the answer.

回答1:

To match everything up to a certain character X, the simplest should be;

[^X]*

Simple refiddle to show it.

回答2:

Another flavour, which is close to what you had in mind originally:

(.*?)X

Greedy capture ? is the trick here. You will need to take the first captured group in code if you want to exclude X character from the result.
