c#读取XML多级子节点

作者：袖梨 2022-06-25

代码如下

复制代码

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

XmlDocument doc =newXmlDocument();

doc.Load(xmlFilePath);//加载XML文件

stringrst ="";

//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 studentNodeinstudentNodeList)

{

//通过Attributes获得属性名字为name的属性

stringname = 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;

if(courseNodeList !=null)

{

foreach(XmlNode courseNodeincourseNodeList)

{

rst += courseNode.Attributes["Name"].Value+",";

}

rst +="
";

}

Response.Write(rst);
