How to remove <Data> element from the tree using Linq to XML, Lamda Expression in C#? where <Data> is a auto generated element and XML structure may vary.

Answer 1

it all depends on what element you want to remove but you can use something like this

XDocument people = XDocument.Load("filenamre.xml");
IEnumerable<XElement> Person = people.Element("Person");
//gets  the element you want to remove based on value 
XElement name = Person.Where(p => p.Element("xxx").Value == "1").FirstOrDefault();
//removes the name 
name.Remove();
//create a new file without the element 
people.Save(Server.MapPath("Newfilenamre.xml"));

Answer 2

Removing element other than first one. Means only first must be there rest all must be deleted.
