实例应用：

string strXmlFile = Server.MapPath("TestXml.xml");
XmlControl xmlTool = new XmlControl(strXmlFile);

//
// dgList.DataSource = xmlTool.GetData("Book/Authors[ISBN=/"0002/"]");
// dgList.DataBind();

// 更新元素容
// xmlTool.Replace("Book/Authors[ISBN=/"0002/"]/Content","ppppppp");
// xmlTool.Save();

// 添加一新
// 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();

// 除一指定的所有容和性
// xmlTool.Delete("Book/Author[ISBN=/"0004/"]");
// xmlTool.Save();

// 除一指定的子
// xmlTool.Delete("Book/Authors[ISBN=/"0003/"]");
// xmlTool.Save();
