生成XML文件

            Dot3D dot1 = this.scenControl.WpToLp(e.X, e.Y);

            //添加第一行编码等格式。

            //创建第一个大节点
            XmlElement xml = StandardXml.CreateElement("XML");

            XmlElement firstXML = StandardXml.CreateElement("firstXML");

            XmlElement Xzhou = StandardXml.CreateElement("Xzhou");
