Using regex to replace a string that is not the replace string

Question

I would like to replace all string that do not equal this: readWriteDataGroup="Everyone" on a file I have open in Notepadd++. One of the strings that it will need to replace has this string: readWriteDataGroup="E_MOD_WSP_64"

So I have been doing this manually but there is over 1000000 lines which is not feasible to be done manually.

How can I do this via regex?

What is your regEx? search key readWriteDataGroup="Everyone", and replace value readWriteDataGroup="E_MOD_WSP_64", why would not this work? — Popeye

What is a "string that do not equal readWriteDataGroup="Everyone""? What does it mean that "One of the strings [...] has this string"? — logi-kal

Please, edit your question and add example lines from your file and expected result. As is, your question is really unclear. — Toto

If you search for (readWriteDataGroup=")(?!Everyone")[^"]*(") and replace it with $1X$2 then all the lines that do not contain Everyone in the quotation marks will be replaced with an X.

How that works:

In the search string

(readWriteDataGroup=") will match readWriteDataGroup=" and save it as $1
(?!Everyone")[^"]* will match any string that isn't Everyone
(") will match a trailing " and save it as $2

In the replacement:

$1 is the first capture group (readWriteDataGroup=")
X is the replacement text
$2 is the second capture group (")

In Notepad++, make sure you select the "Regular Expression" button on the Replace dialog.
