I need a regex to match first sentence of the string

Question

I'm trying to come up with a regex which would match the first sentence of the string. I don't need anything too complex, just a sentence that ends with ". " or "! " or "? " note the space after, so that the sentence "I need this domain.com! " would match. I didn't find anything on regexlib.com either. So far I'm stuck with this:

([^.|?|!]*)[\.\s\?\s\!\s]

It's not really working. If I try to match

"I need this domain.com! Another sentence. And another sentence."

I only get "I need this domain." and I need it to be "I need this domain.com!"

Answer 1

Try this :

^.*?[\.!\?](?:\s|$)
