Using Regular Expression Groups in Search and Replace

I needed to convert a series of numbers as in:

          19473

          20390

          22797

          23116

          ..

into

          list.Add(19473);

          list.Add(20390);

          list.Add(22797);

          list.Add(23116);
          ...

While I am not adverse to doing this manually or thru some macro, I was staring at 10000 of these so I can just hear my old boss saying "You are not lazy enough."

The solution is to use regular expressions. Using NotePad++,

 

The key here was to enclose in parenthesis the search pattern and reference that in the replace string as \1.

Sweet!
