How to find same variable with different value using RegEx?-CodePudding

Here is the example.

0x13F4E010 = 4 new items
0x13F4E010 = 5 new items of clothing available

I only want to find the same variable with different value with RegEx, so i can edit it manually.

So, basically i only need help to find these duplicated variable behind different value.

0x13F4E010 = 
0x13F4E010 =

Sorry for bad english. Thank you in advance.

I find this example in internet

^(.*)(\W\1) $

but that only find duplicate with same variable and same value. Like this...

    0x14C79222 = Camo Sweatpants
    0x14C79222 = Camo Sweatpants

A sample regex that can do the job is

^(\S ) = (. )\r?\n\1 = (. )$

See the regex demo.

Details:

^ - start of a line
(\S ) - Group 1: one or more non-whitespace chars
= - a = with one space on both sides
(. ) - Group 2: one one or more chars other than line break chars as many as possible
\r?\n - CRLF or LF ending
\1 - same value as in Group 1
= - a = with a space on each side
(. ) - Group 3: one one or more chars other than line break chars as many as possible
$ - end of a line.

Note you might need an (?m) inline regex option (or code equivalent) to make ^ and $ match start/end of each line instead of the whole string (depends on the environment).
