Counting characters in a line in notepad++

Question

I'm trying to count the amount of times a character in a single line appears to then edit the lines which it does.

Say i have a line that goes:

\serv\file\subfile\subsubfile\subsubsubfile

Is there any way I can count the amount of times the \ character appears, and if it doesn't appear more than say twice, clear the line and leave it blank?

Answer 1

find ^([^\\]*[\\]?[^\\]*){0,2}$

replace with empty string
