using regex on golang and having hard time to group three names from the following statements:
Hello Planet Earth 2022 - R1 3 Hell John v Tom v Ford
Hello World 2022 - R2 3 Hell - John v Tom v Ford
I'm trying to group "John" "Tom" "Ford" with the following regex:
^(?i). ? . R\d 3 Hell (. ?)[,|v] (. ?)[,|v] (. ?)$
The issue is that it groups "- John" for second statement and I need "John" only.
Any ideas how can it be adjusted?
thanks

Not sure how correct it is, but having tested here, I came up with this...
^(?i). ? . R\d 3 Hell[\s-]* (. ?)[,v] (. ?)[,v] (. ?)$

As you seem to match single spaces, you can optionally match a dash and a space.
Note that the last . does not have to be non greedy as it is the last part of the pattern, and the character class [,v] does not need a pipe char if you do not intent to match that as a character.
^(?i). ? . R\d 3 Hell (?:- )?(. ?) [,v] (. ?)[,v] (. )
