詳細介紹c#讀取XML多級子節點

string xmlFilePath = "D:\\log_xml\\MarInfo.xml"; //Server.MapPath(@"相對路徑如/xml/test.xml");           XmlDocument doc = new XmlDocument();           doc.Load(xmlFilePath);//載入XML檔案           string rst = "";           //使用xpath運算式選擇文檔中所有的student子節點           XmlNodeList studentNodeList = doc.SelectNodes("Root/MarketList/Market");           if (studentNodeList != null)           {               foreach (XmlNode studentNode in studentNodeList)               {                   //通過Attributes獲得屬性名稱字為name的屬性                   string name = studentNode.Attributes["MarketName"].Value+":";                   rst+= name;//通過SelectSingleNode方法獲得當前節點下的SubMarketList子節點                   XmlNode coursesNode = studentNode.SelectSingleNode("SubMarketList");//通過ChildNodes屬性獲得courseNode的所有一級子節點                   XmlNodeList courseNodeList = coursesNode.ChildNodes;                   if (courseNodeList != null)                   {                       foreach (XmlNode courseNode in courseNodeList)                       {rst += courseNode.Attributes["Name"].Value+",";}                       rst += "<br/>";                   }}           }           Response.Write(rst);
