讀取xml

//讀取xml
        XmlDocument xdoc = new XmlDocument();
        xdoc.Load(Server.MapPath("/App_Data/data.xml")); XmlElement root = xdoc.DocumentElement; //獲取根節點 Response.Write(root.GetElementsByTagName("price")[0].InnerText);

//寫入xml
        XmlDocument xdoc = new XmlDocument();
        xdoc.Load(Server.MapPath("/App_Data/data.xml")); XmlElement root = xdoc.DocumentElement; //獲取根節點 root.GetElementsByTagName("price")[0].InnerText = "200"; xdoc.Save(Server.MapPath("/App_Data/data.xml"));
