How do I replace text with a linebreak using regular expressions
I have written a program that searches for 'opens' without matching 'closes' in a target file. It produces an output like this:
open
close
open
open
close
In this example here the second 'open' is not immediately followed by a matching 'close', so I consider that an error. My text-editor (editpad) has a regular-expression search/replace feature, which I would like to use to get rid of all correct pairs, so I can notice easily the incorrect situations. I tried replacing the following
open\r\nclose
I thought that this would match the two words and the line-break between them (I'm using Windows). This did not work.
Does anyone have an idea why it didn't?

If you select the Regex mode, your regex will work, but I also suggest making \r optional by appending ? after it to support LF endings, too:
open\r?\nclose
See the screenshot with settings and proof it works in EditPad:
