46trgfbf7:dank420
dp.b2c33:@phill
terry.hj:6@YD9

What have you tried? Have you used one of the regular expression helper sites to try to build a correct regular expression to match your data?

Hello, @ani-rodet, scott-sumner and All,

Ah, OK, I won’t abandon you, with your big text ;-))

So, open the Replace dialog ( Ctrl + H )

SEARCH (?-si)^.+@[a-z]+\.(com|org|net|int|edu|gov|mil)(:\w+)?\R|^.+\R

REPLACE ?1$0

• Select the Regular expression search mode

• Tick the Wrap around option

• Click on the Replace All button

Et voilà !

Notes :

• I took the main top-level-domains from this link :

https://en.wikipedia.org/wiki/List_of_Internet_top-level_domains

• For instance, here are below, the different parts of the regex, with, accordingly, the first line dozyyqprodus@mybuy.com:dory34

(?-si)^     .+       @  [a-z]+  \.  (com|org|net|int|edu|gov|mil)  (:  \w+  )?    \R     |         ^.+            \R

      >dozyyqprodus  @  mybuy    .             com                  : dory34     CRLF    or  ALL line contents   CRLF

• Just try to guess how this regex works and, please, read some regex documentation ;-) Indeed, that regex is simply made up of basic consecutive structures and it’s not very difficult to build !

• Regarding the Replacement part,

  • If group 1 exists, (com|org|net|int|edu|gov|mil), all the matched string is re-written

  • If not, the entire line, with its line-break, is deleted

Best Regards,
