实例应用:
string strXmlFile = Server.MapPath("TestXml.xml"); XmlControl xmlTool = new XmlControl(strXmlFile);
// 數據顯視 // dgList.DataSource = xmlTool.GetData("Book/Authors[ISBN=\"0002\"]"); // dgList.DataBind();
// 更新元素內容 // xmlTool.Replace("Book/Authors[ISBN=\"0002\"]/Content","ppppppp"); // xmlTool.Save();
// 添加一個新節點 // xmlTool.InsertNode("Book","Author","ISBN","0004"); // xmlTool.InsertElement("Book/Author[ISBN=\"0004\"]","Content","aaaaaaaaa"); // xmlTool.InsertElement("Book/Author[ISBN=\"0004\"]","Title","Sex","man","iiiiiiii"); // xmlTool.Save();
// 刪除一個指定節點的所有內容和屬性 // xmlTool.Delete("Book/Author[ISBN=\"0004\"]"); // xmlTool.Save();
// 刪除一個指定節點的子節點 // xmlTool.Delete("Book/Authors[ISBN=\"0003\"]"); // xmlTool.Save();
