How to replace all lines except one word per line using a regular expression-CodePudding

How do you replace all lines except one word per line using a regular expression?

I tried the following regex that mostly works but all the lines after the last match remain.

Find what: (?s)(.*?property": ")(\w )(.*?$)

Replace with: \2\n

Simplified text file:

random lines of text
{
    "property": "my1Value",
    "property": "my2Value",
    "property": "my3Value",
}
more random lines of text

Expecting one word per line:

my1Value
my2Value
my3Value

CodePudding user response：

You could just match single characters when the main pattern doesn't match. These will then get replaced by the empty string (since the capture groups captured nothing):

Find: (?s)"property": "([^"] )".*?(\R)|.

Replace: \1\2
