Notepad ++：正则表达式作为替换

Question

I'm busy inserting my url aliases into a database. And need to make insert queries from the list of values i have.

A few items from my list:

(NULL, 'tag=23525','2807016'),
(NULL, 'tag=23525','10165'),
(NULL, 'tag=23525','12165'),

I'd love to have a regex expression which can find tag=23525 and can replace it with the number behind it. So the list will end up looking like this:

(NULL, 'tag=2807016','2807016'),
(NULL, 'tag=10165','10165'),
(NULL, 'tag=12165','12165'),

I've managed to find the text tag=23525 (wow so hard). But i'm stuck with the finding (the replace) of the number behind.

I can find the last number easily with this regex but can't replace with this regex:

^[^,]*,[^,]*,[^,]*\\b(\\w+)\\b

How am i able to find and replace tag=23525 with the match found from the regex?

(?<=tag=)\d+('\s*,\s*')(\d+)

You can use this.Replace by $2$1$2 or \\2\\1\\2 .See demo.

Was a little tricky but here is how you can do it:

\d+(',')(\d+)

and replace with

$2$1$2
