Regular expression to match ) under certain conditions

Question

I am trying to match ) if there is a ( and two numbers to the left of it.

Example "(55)" I want to match ) in "(55)"

I do not want to match "(hello world 55)"

I currently have the following as my regex:

     \(\d+\)

It matches "(55)" but I just want the ) in it. Is there a way to get a certain character by placement in a regex? Or do you have a better solution?

`\(\d+\K\)`, `(?<=\(\d+)\)`, etc. There are a lot of solutions and workarounds. — Wiktor Stribiżew, Jul 06 '20 at 15:17
@WiktorStribiżew I was going to answer this and saw your comment, why don't you post it as an answer. It's a nice answer since it can have `\K` or look behind — Federico Piazza, Jul 06 '20 at 15:21
Please try this [`(?<=\(\d{2})\)`](https://regex101.com/r/KROBYi/2) — , Jul 06 '20 at 15:28

There are multiple ways to match what you want.

For instance, you can use \K to rest the previous match:

\(\d+\K\)

Using positive lookbehind

(?<=\(\d+)\)

Also capturing the content for the match

\(\d+(\))
