Regex replace matched and remove not matched

Question

Is there a way to replace part of matched line and remove all not matched lines with only one query using Notepad++ Replace tool?

For example: (string in quotes should be replaced with 123)
input:

There is line with "quoted" part
There is another line

expected result:

There is line with "123" part

Answer 1

As a pattern use

([^"]*?)^(.*?)".*?"(.*)([^"]*$)

and as a replacement use

$2"123"$3

Answer 2

My best shot:

Find

(^[^\r\n]*?)("quoted")([^\r\n]*?)$((\r\n)?(?![^\r\n]*?"quoted"[^\r\n]*?$).*?$)+

replace with

$1"123"$3

For every pattern between "" Ωmega answer is good, this one lets you replace a specific pattern and not everything between quotes.

Explanation:

• (^[^\\r\\n]*?) : Find any character sequence without newlines (and non greedily)
• ("quoted") : followed by "quoted"
• ([^\\r\\n]*?)$ : till the end of the line
  • ((\\r\\n)? :we are in the new line
  • (?![^\\r\\n]*? : look ahead (negative) to avoid a non-newline character sequence
  • "quoted"[^\\r\\n]*?$) : followed by "quoted"
• .*?$)+ : one or more times
