Answer 1

EDIT: Okay, with further editing, it's clearer what you want to do, and as it happens it's significantly easier than you're making it, thanks to the Remove extension method on IEnumerable<T> where T : XNode:

string target = txt.Text.Trim();
doc.Descendants("start")
   .Elements("site")
   .Where(x => x.Value == target)
   .Remove();

That's all you need.
