I have following string dfed  operator  11 -  145. I am trying to match string operator  11 and inside this matched string, i am trying to match string 11. Currently I successfully matched operator 11 with regex ((O|o)perator(i|I)?\s*)\d+(?=\s*(-|_)\s*\d+). As I am in javascript, I can not use lookbehinds.

Is my approach correct? Is there any way to accomplish this in regex? How can i match string 11 inside previously matched string operator  11?
