读取响应XML文件

本文关键字：文件 XML 响应 读取 | 更新日期: 2023-09-27 17:50:12

我想用c# LINQ读取下面的XMLfile。
我在c#中尝试过这个代码。但无法获取地址元素数据。

代码:

 XNamespace ns = "http://www.w3.org/2001/XMLSchema";
 XNamespace nsa = "http://www.w3.org/2001/XMLSchema-instance";
 var Address = from r in XDocumentdata.Descendants(ns + "Address")
               select new
                     {
                       Locality = r.Element(nsa + "Locality").Value,
                       CountryRegion = r.Element(nsa + "CountryRegion").Value
                     };
 foreach (var r in Address)
 {
     string CountryRegion = r.CountryRegion;
     string Locality = r.Locality;
 }

XML:

读取响应XML文件

您使用了错误的命名空间。文档的根命名空间(由XML文档的未别名xmlns属性表示)是http://schemas.microsoft.com/search/local/ws/rest/v1。

使用nsa的当前值

  1. 创建一个匹配XML和结构的类/模型将XML反序列化为对象或集合。
    2. 如果你需要，可以使用Linq来处理收集。

看看https://msdn.microsoft.com/en-us/library/tz8csy73(v=vs.110).aspx

你能试一下吗? 

var xmlDoc = new XmlDocument();
xmlDoc.Load("your xml path");
var address = xmlDoc.GetElementsByTagName("Address");

我现在可以访问地址元素里面的元素了
