Regex to match only last 3 characters when there are more

Question

With

(x)?xxx

I get match xxx and xxxx with

test1xxxblah
test2xxxxblah

whereas I would like last xxx for test2xxxx

I'm really not proficient at regex I can't see what to use

Maybe you just need to add `$` at the end? `(x)?xx$`. Or `x{3}$`, `x{2,3}$`? — Wiktor Stribiżew, Jun 04 '21 at 09:17
@WiktorStribiżew thanks so I updated it's not especially at the end of a line — user310291, Jun 04 '21 at 09:20
Then `.*((x)?xxx)`, see https://regex101.com/r/MHCKZx/2 and get Group 1. — Wiktor Stribiżew, Jun 04 '21 at 09:21
It ***captures*** what you need. It does not matter what is matched. — Wiktor Stribiżew, Jun 04 '21 at 09:22
Not sure what you want: `xxx(?!x)` maybe? or with a capture group: `x*(xxx)` — JvdV, Jun 04 '21 at 09:23
@WiktorStribiżew ah it seems it's in group I have to learn group deeper then — user310291, Jun 04 '21 at 09:24
