If you want the alternations to match at the same starting position, you might be able to fiddle something together with look-ahead groups (not sure it works), but generally that doesn't work very well.

You could try to match once, reset pos to the previous starting position, remove the regex that caused the match and retry again. But I don't think that's very efficient.

If you don't want to match at the same position, you can use the /g modifier in a while loop to match multiple times.
