类似于这样：XmlDocument xmlDoc=new XmlDocument();
xmlDoc.Load("data.xml");
XmlNode pnode=xmlDoc.SelectSingleNode("//data[@Name='渝中]");//查找
XmlElement xe1=xmlDoc.CreateElement("subdata");//创建一个节点
xe1.SetAttribute("Name","观音桥");//设置该节点Name属性
xe1.SetAttribute("Value","观音桥");//设置该节点Value属性
xe1.SetAttribute("Code","TTK010107");//设置该节点Code属性
pnode.AppendChild(xe1);//添加到节点中 
xmlDoc.Save("data.xml");
