c# XML读取

System.Xml 命名空间

1.通过 XmlDocument获取稳定内容

2.通过XmlNodeList 找到节点数据

 

private void List_Click(object sender, RoutedEventArgs e) { string xmlStr = getData(); StringBuilder rtn = new StringBuilder(); XmlDocument xmlDoc = new XmlDocument(); xmlDoc.LoadXml(xmlStr); XmlNodeList xmlNodeList = xmlDoc.GetElementsByTagName("root"); foreach (XmlNode xmlNode in xmlNodeList) { //家长节点 XmlNodeList childXmlNodes1 = xmlNode.ChildNodes; foreach (XmlNode childXmlNode1 in childXmlNodes1) { if (childXmlNode1.Name == "resultInfo") { //成员列表 XmlNodeList childXmlNodes2 = childXmlNode1.ChildNodes; foreach (XmlNode childXmlNode2 in childXmlNodes2) { if (childXmlNode2.Name == "NAME") { rtn.Append(childXmlNode2.InnerText); } } } } } }
 private string getData() { return "<?xml version=\"1.0\" encoding=\"utf-8\"?>" + @" <root> <resultInfo> <NAME>姓名</NAME> <SEX>性别</SEX> <error_msg> 成功！或者error:xxx </error_msg> <remark>备注</remark> </resultInfo> </root> "; }

 

读取方法扩充

public static LoginResponse GetLoginResponse(string xmlStr)
{
    LoginResponse response = new LoginResponse();

    XmlDocument xmlDoc = new XmlDocument();
    xmlDoc.LoadXml(xmlStr);
    
    XmlNode errorNode = xmlDoc.SelectSingleNode("//Error");
     if (errorNode != null)
     {
         response.ResultErrorCode = (errorNode.SelectSingleNode("ErrorCode")).InnerText;
         response.ResultErrorText = (errorNode.SelectSingleNode("ErrorText")).InnerText;
         response.ResultErrorDescription = (errorNode.SelectSingleNode("ErrorDescription")).InnerText;
     } 
    
    return response;
}

数据：
<?xml version="1.0" encoding="UTF-8"?>
<RESULT>
<Error>
<ErrorCode>-1</ErrorCode>
<ErrorText>ErrorText</ErrorText>
<ErrorDescription>ErrorDescription</ErrorDescription>
</Error></RESULT>
