Question

我正在尝试使用XMLDocument（DItem＆gt;＆gt; Title）解析xml元素下面是我的代码，但不知怎的，我没有抓住它....任何帮助？

XmlDocument xmldoc = new XmlDocument();
            XmlNamespaceManager xmlns = new XmlNamespaceManager(xdoc.NameTable);
            xmlns.AddNamespace("DItems", "http://namespace.xsd");
            xmldoc.Load(url); 

        var title = xmldoc.SelectNodes("content", xmlns);
        foreach (XmlNode node in title)
        {
            string title = node.Attributes["Title"].Value;
            //this.ddlTitle.Items.Add(new ListItem(title));
        }

这是我的XML：

    <?xml version='1.0'?>
<root xmlns="http://www.w3.org/2005/Atom">
  <title type="text">title</title>
  <entry>
    <content type="application/xml">
      <Items xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://www.namespace.xsd">
        <CatalogSource Acronym="ABC" OrganizationName="organization name" />
        <Item Id="28466" CatalogUrl="url">
          <DItem xmlns:content="http://namespace.xsd" TargetUrl="http://index.html" Title="my title1">
            <content:Source Acronym="ABC" OrganizationName="ABC" />
          </DItem>
        </Item>
      </Items>
    </content>
  </entry>
  <entry>
    <content type="application/xml">
      <Items xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://www.namespace.xsd">
        <CatalogSource Acronym="ABC" OrganizationName="organization name" />
        <Item Id="28466" CatalogUrl="url">
          <DItem xmlns:content="http://namespace.xsd" TargetUrl="http://index.html" Title="my title2">
            <content:Source Acronym="ABC" OrganizationName="ABC" />
          </DItem>
        </Item>
      </Items>
    </content>
  </entry>
  <entry>
    <content type="application/xml">
      <Items xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://www.namespace.xsd">
        <CatalogSource Acronym="ABC" OrganizationName="organization name" />
        <Item Id="28466" CatalogUrl="url">
          <DItem xmlns:content="http://namespace.xsd" TargetUrl="http://index.html" Title="my title3">
            <content:Source Acronym="ABC" OrganizationName="ABC" />
          </DItem>
        </Item>
      </Items>
    </content>
  </entry> 
</root>

var xmldoc = new XmlDocument();
var xmlns = new XmlNamespaceManager(xmldoc.NameTable);
xmlns.AddNamespace("DItems", "http://www.namespace.xsd");
xmldoc.Load(url);

var titleNodes = xmldoc.SelectNodes("//DItems:DItem/@Title", xmlns);

var result = titleNodes.Cast<XmlAttribute>().Select(a => a.Value).ToList();

输出（对象列表）：

my title1
my title2
my title3

XML使用XMLDocument提取属性
