解析用C＃复杂的XML [英] Parsing complex XML with C#

问题描述

我试图解析用C＃一个复杂的XML，我使用LINQ去做。基本上，我做的到服务器的请求，我得到XML，这是代码：

I am trying to parse a complex XML with C#, I am using Linq to do it. Basically, I am doing a request to a server and I get XML, this is the code:

XElement xdoc = XElement.Parse(e.Result);
this.newsList.ItemsSource = 
  from item in xdoc.Descendants("item")
  select new ArticlesItem
  {
    //Image = item.Element("image").Element("url").Value,
    Title = item.Element("title").Value,
    Description = this.Strip(item.Element("description").Value).Substring(0, 200).ToString()
  }

这是XML结构：

<item>
  <test:link_id>1282570</test:link_id>
  <test:user>SLAYERTANIC</test:user>
  <title>aaa</title>
  <description>aaa</description>
</item>

我怎么能访问到性能测试：比如link_id

How I can access to the property test:link_id for example?

谢谢！

推荐答案

目前您的XML是无效的，因为测试命名空间中未声明，你可以声明它是这样的：

Currently your XML is invalid since the test namespace is not declared, you can declare it like this:

<item xmlns:test="http://foo.bar">
  <test:link_id>1282570</test:link_id>
  <test:user>SLAYERTANIC</test:user>
  <title>aaa</title>
  <description>aaa</description>
</item>

有了这个，你可以使用的XNamespace 资格你想用正确的命名空间的XML元素：

Having this you can use XNamespace to qualify the XML element you want with the correct namespace:

XElement xdoc = XElement.Parse(e.Result);
XNamespace test = "http://foo.bar";
this.newsList.ItemsSource = from item in xdoc.Descendants("item")
                            select new ArticlesItem
                            {
                                LinkID = item.Element(test + "link_id").Value,
                                Title = item.Element("title").Value,
                                Description = this.Strip(item.Element("description").Value).Substring(0, 200).ToString()
                            }
