replacing "\N" with regex

Can someone help me fix this notepad++ regex so that it will replace the text \N with a space?

((?=.*?,Default)[^\r\n]*)(\N)

I'm looking to replace all instances of the text \N only on lines that have ,Default on it.

I suggest

(?:\G(?!^)|^(?=.*,Default)).*?\K\\N

See the regex demo.

Details:

  • (?:\G(?!^)|^(?=.*,Default)) - a start of the line location that contains ,Default substring (^(?=.*,Default)) or the end of the previous successful match (\G(?!^), as \G matches the start of string/line, its position must be subtracted with a negative lookahead)
  • .*? - any 0+ chars other than line break chars, as few as possible
  • \K - a match reset operator
  • \\N - a literal \N substring.

A test in Notepad++:

\NSome text,Default\Nand more here\N
\Ntext \N text ,Default
New line \N\N\N
