Regex to capture all numbers in a string that ends with a number

I'm trying to write a regex that captures all the numbers in a string BUT only if the string ends with numbers.

I worked out the pattern would require a repeating capture group:

^(\D*(\d+))+$

So

My problem is that it seems that in repeated capture groups you only get the last match returned to you. (demo)

Can anyone show me where I'm going wrong?

You may use this regex with a lookahead:

\d+(?=(?:\w+\d)?\b)

RegEx Demo

RegEx Breakdown:

  • \d+: Match 1+ digits
  • (?=: Start Lookahead assertion
    • (?:\w+\d)?: Optionally match 1 or more word characters followed by a digit
    • \b: Word boundary
  • ): End Lookahead assertion
