Answer 1

I think there's two problems with the regex. The first is that the . near the end in (?.+) is not matching newlines. So you could modify it to:

(?(.|[\r\n])+?)

Or you could specify RegexOptions.Singleline as an option to the regex. The only thing the option does is make the dot match newlines.

The second problem is that .+ matches as many lines as it can. You can make it non-greedy like:

(?(.|[\r\n])+?(?=\r\n\r\n|$))

This matches the least amount of text that ends with an empty line or the end of the string.
