Question

Okay, I can find a Regex match in a string, and do some captures.
Now, what if my string has many matches? Let’s say my code finds out the number inside parenthesis in a string. The code will find the number in a string like

(5)

But what if the string is

(5) (6) (7)

I need a way to iterate through these three elements. I’ve seen tutorials, but they seem to only talk about one-time matches…

If I understand correctly, you could use the String#scan method. See documentation here.
