            //创建Xml
            XDocument doc = new XDocument(new XElement("Data",
                new XElement("aaa",
                    new XElement("name", "lily"),
                    new XElement("age", "10")),
                new XElement("aaa",
                    new XElement("name", "jak"),
                    new XElement("age", "110"))));

            //为Xml之追加节点，并且设置属性
            doc.Element("Data").Add(
                new XElement("name",
                    new XAttribute("type", "11"), "asasas"),
                    new XElement("age", "222"));

            Console.WriteLine("===========删除前============");
            Console.WriteLine(doc.ToString());
            //删除节点值为lily 的节点
            var s1 = from s in doc.Element("Data").Elements("aaa") where s.Element("name").Value == "lily" select s;

            Console.WriteLine("===========删除后============");
  
            s1.Remove();
            doc.Add(s1);
            Console.WriteLine(doc.ToString());
