Resolved: Regex - Extract string between characters if they exist

Question:

I would need to use RegEx to extract a string between characters if they exist (The colon character).
Examples:

In all cases, I want the result.

2294 001 267

Thank you all.

You can use this regex to match them all

(?:^|:)\s?([A-Z\d]+(?: [A-Z\d]+)+)(?:$|:)

NOTE: As you did not mention what language you’re using I decided to not use lookarounds. So you have to get the first group from the match.

If you have better answer, please add a comment about this, thank you!
