If you want to limit it to just the one bit that matches inside the parenthesis, you have to match the entire string, too, so that it will also be replaced. In your example, the \\1 is being set to "Release" and the "/build Release" is being replaced with \\1 in the entire input string. So in effect, you erased the "/build " from in front of it. What you want is to erase the whole string, except for the "Release", right?

Thank you... That makes sense, now that I think about it.
