Replace regexp capture-group in Notepad++?

Question

Quick question: I have a regexp, ^(?:\b[A-Z]+\b\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

Building Groups with (?<1>....),(?<2>....), for substitution using \1 \2

Answer 2

Do it this way:

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

Replace with: \1 \2

Answer 3

Try using:

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

And replace with:

\1\2
