使用XPath进行XML解析.C#

Question

我有一些问题,也许是愚蠢的问题.

我有这个网址:http: //flibusta.net/opds/opensearch？searchTerm =Тол&searchType =books

我想像这样解析响应:

string search_link = "http://flibusta.net/opds/opensearch?searchTerm=???&searchType=books";

_document = new XPathDocument(search_link);

XPathNavigator navigator = _document.CreateNavigator();
XmlNamespaceManager ns = new XmlNamespaceManager(navigator.NameTable);
XPathNodeIterator nodes = navigator.Select("/feed/title");

while (nodes.MoveNext())
{
        XPathNavigator currentNavigator = nodes.Current;
        string title = currentNavigator.Value;
        Trace.WriteLine(title);
}

但节点返回零结果.无法理解我做错了什么.

谢谢,

帕维尔.

忘记没有命名空间的XML.试试下面的例子,它适用于我:

var document = new XPathDocument("http://flibusta.net/opds/opensearch?searchTerm=%D0%A2%D0%BE%D0%BB&searchType=books");
XPathNavigator navigator = document.CreateNavigator();
var ns = new XmlNamespaceManager(navigator.NameTable);
ns.AddNamespace("atom", "http://www.w3.org/2005/Atom");

XPathNodeIterator nodes = navigator.Select("/atom:feed/atom:title", ns);

while (nodes.MoveNext())
{
        XPathNavigator currentNavigator = nodes.Current;
        string title = currentNavigator.Value;
        Trace.WriteLine(title);
}
