regex - Replace regexp capture-group in Notepad++?

Question

Quick question: I have a regexp, ^(?:[A-Z]+s+)+(.*)d{8}, that gives two capture groups. I would like to replace capture group 1 with a whitespace. Is that possible?

If I do replace with: 1 it replaces TEST TESTER Hello, world. Another word here. 75793250 -> with Hello, world. Another word here. I want this result: TEST TESTER 75793250. Replacing the 1 with a whitespace.

Answer 1

Try using:

^((?:[A-Z]+s+)+)(?:.*)(d{8})

And replace with:
