string xmlFilePath = "D:\\log_xml\\MarInfo.xml"; //Server.MapPath(@"相对路径如/xml/test.xml");

           XmlDocument doc = new XmlDocument();

           doc.Load(xmlFilePath);//加载XML文件

           string rst = "";

           //使用xpath表达式选择文档中所有的student子节点

           XmlNodeList studentNodeList = doc.SelectNodes("Root/MarketList/Market");

           if (studentNodeList != null)

               foreach (XmlNode studentNode in studentNodeList)

                   //通过Attributes获得属性名字为name的属性

                   string name = studentNode.Attributes["MarketName"].Value+":";

                   rst+= name;

//通过SelectSingleNode方法获得当前节点下的SubMarketList子节点

                   XmlNode coursesNode = studentNode.SelectSingleNode("SubMarketList");

//通过ChildNodes属性获得courseNode的所有一级子节点

                   XmlNodeList courseNodeList = coursesNode.ChildNodes;
