I am trying to use Notepad ++ to delete emails that end in @domain2.serverdata.net

here is a string example:

smtp:name@domain1.com;SMTP:name@domain2.com;smtp:name@domain2.serverdata.net;smtp:name@domain3.com;smtp:name_e4d1fe3d-e985-40d0-bc65-32c57c9b14d1@domain2.serverdata.net

I was hoping to use:

;smtp:.*@domain2.serverdata.net

but it captures SMTP:name@domain2.com as well

Notepad++ - Replace with Regular Expression, This tutorial about using regular expression on Notepad++.Duration: 12:57 Posted: 2 Feb 2019 regex in notepad++ Searching a string using the ‘ Find ‘ or ‘ Find & Replace ‘ function in text editors highlights the relevant match (e.g. searching ‘ le ‘ highlights it inside words such as ‘app le ‘, ‘p le ase’ etc).

Regexes will usually capture as much as possible. For instance: START.*STOP applied to the following text:

STARTsghlegdSTOPfsgikbSTARTsvdinusSTOPwegtgw

will capture this part:

STARTsghlegdSTOPfsgikbSTARTsvdinusSTOPwegtgw
^------------------------------------^

In your case, the .* captures everything up to the last instance of @domain2.serverdata.net. You don't want to use . (any character), you want to use "any character except '@'" which is written like this: [^@]. So your full regex would be smtp:[^@]*@domain2\.serverdata\.net. I also dropped the initial ; since it would prevent you from capturing the first mail address.

  • This one works on regex101.com but it gives an error "Find: Invalid regular expression" for me when i test in Notepad++ v7.5.4 (32-bit), the question says the context is Notepad++
  • add a * after that leading ';' and this is the best answer
  • Thanks @Gus, I've added a ? instead of *
  • If you drop the initial ; you could possibly end up with ;; in the result.
  • true, I guess starting with ;? would be ideal
  • Note that this will not match an email address at the start.
  • But now you might possibly get ;; in the result.
  • How is that? Can you give an example?
  • See the replacement value regex101.com/r/vbjWnK/1 but perhaps that is ok with the OP.
  • Nicely spotted, gave it another go, it still has a shortcoming of leaving a semicolon behind in case a @domain2.serverdata.net email appears last in the list but maybe it good enough for him
