Your regular expression fails for me if I put windows line endings in the string ("\r\n") instead of Linux ones ("\n"). The option
This is, because . does match only \r then, after that the regex demands to get a - but there is \n, so it fails.
So you have 3 options:
- Demand the client to deliver only Linux-Endings, but depending on the tech knowledge of the client that may be impossible
- Normalize the input before feeding to the RE-scan, which should be the easiest one
- replace the dots that shall match line endings by
(?:\r|\n|\r\n), but the output needs to be cleaned up as well.
