Invert regex match

Question

[vpsev3]

Hello,

I would like to invert my regex match

Example:

sssd;RS=93298723;f

My current regex :

RS=\d*

This regex would match RS=93298723, I would want to invert the match, see demo here https://regex101.com/r/PGkwA5/1

Thank you.

for which tool ? what is "invert" a regex result ? RS=A would "invert" the result..

I edited my question

I'm trying to invert my regex match, for example, I would like to match everything except RS=93298723 (the digits could change)

This is because I'm creating a CSV file with variants to compare them, I will create my own tool in python

[Pierre Lindenbaum]

aren't you looking for grep -v -f patterns.txt ?

[vpsev3]

I'm on EmEditor, I try to select everything except RS=(numbers)

[vpsev3]

I have this regex101.com/r/PGkwA5/1

But I would like to do the opposite

In Python, you can try this (?!RS=\d+)

This is a negative lookahead assertion.

I would need to do this on Emeditor or another text editor

([^0-9-RS=]+)
