Regular expression, picking numbers before a text

Question

I wanted a regular expression to catch the minutes in a string with this format:

1 min
10 min

I made that expression. \d(?= min)

The problem is that it only takes the last number, the closest to the min. How would I get the all numbers?

Answer 1

If you put a + after \d already works. That way you mean a number that occurs once or more. Being without the + means only once.

\d+(?= min)
