I am trying to match a string with regex. Here are examples of how it should work

Should get content between center tags.

<center>match this text, can contain anything<\center>

Should get all of the content after the center tag

<center>match this text, can contain anything

I tried using look positive lookahead etc but I wasn't able to get it work

(<center>)(.*)(?=<\/center>)

for example, this regex doesn't match all of the content if the closing tag is not present. Any help would be so good. Thanks.

It is just `(.*?)(?=<\/center>|$)` – Wiktor Stribiżew Jan 26 '22 at 11:46
@WiktorStribiżew Thank you! This never crossed my mind, I thought the answer would be easy but I didn't think of this for some reason. – Sibyl Jan 26 '22 at 11:48

Or `[\s\S]*?` instead of `.*?` when the tags are on different lines, since the `.` (dot) usually doe not match line break chars. – Bart Kiers Jan 26 '22 at 11:50

@BartKiers I'm using s tag to match ```.``` to match new lines. ty – Sibyl Jan 26 '22 at 11:57
