I want to match a regex pattern in string processor (revision V00) with using pattern ^processor +[\S]+ [\S]+ with . I want the (revision V00) to be optional as it may not be present everytime in the string.

I tried using ^processor +(?:([\S]+ [\S]))+ with but its not working

You can match an optional part between parenthesis `^processor(?: \([^()]*\))?` https://regex101.com/r/bh9ugD/1 – The fourth bird Jun 29 '23 at 05:48
