You can't select a node without that node containing its child nodes. Such a "selection" would be equivalent to a mutation. You can create a new XElement that is a copy and then mutate the new one:-

 var desireElement = new XElement(existXElement.Where(w => (string)w.Attribute("title") == "Javascript").First());

 desireElement.RemoveNodes();
