      //Step2：创建XML文档对象
            XmlDocument doc = new XmlDocument();

            //Step3：创建第一行描述信息，并添加到doc文档中  Element 与 Node的关系，文档中所有内容都属于Element，其中标签属于Node，
            XmlDeclaration dec = doc.CreateXmlDeclaration("1.0", "UTF-8", null);
            doc.AppendChild(dec);

            //Step4：XML必须包含且仅能包含一个根结点
            XmlElement order = doc.CreateElement("Order");
            doc.AppendChild(order);

            //Step5：给根结点创建子结点
            XmlElement customerName = doc.CreateElement("customerName");
            customerName.InnerText = "张三";
            order.AppendChild(customerName);

            //Step6：给customerName添加子结点
            XmlElement customerNumber = doc.CreateElement("customerNumber");
            customerNumber.InnerText = "100000001";
            order.AppendChild(customerNumber);

            XmlElement items = doc.CreateElement("items");
            order.AppendChild(items);

            //Step6：给结点添加属性
            XmlElement orderItem1 = doc.CreateElement("OrderItems");
            orderItem1.SetAttribute("Name", "手机");
            orderItem1.SetAttribute("Count", "1");
            items.AppendChild(orderItem1);

            XmlElement orderItem2 = doc.CreateElement("OrderItems");
            orderItem2.SetAttribute("Name", "手表");
