XPath默认名称空间 [英] XPath default namespace

问题描述

我对XML文件中的默认名称空间有疑问.

I have a problem with default namespaces in XML file.

<urlset xmlns="http://www.google.com/schemas/sitemap/0.84">
   <url>
      <loc>http://blog.stevex.net/</loc>
   </url>
</urlset>

我正在使用XPathNavigator通过Xpath选择一组节点，如下所示:

I''m using a XPathNavigator to select a set of nodes using Xpath as follows:

XPathNodeIterator result = navigator.Select("/urlset/url/loc");

我没有得到任何结果.
如何在不向XPath表达式添加前缀的情况下解决此问题?

谢谢.

I am not getting any results back.
How can i solve this problem without adding prefixes to XPath expression?

Thank you.

推荐答案

谢谢cmanderson.

我刚刚从XML中删除了默认名称空间.也许我的代码可以帮助某人.

Thank you cmanderson.

I just removed the default namespaces from XML. Maybe my code will help someone.

string RemoveAllDefaulNamespaces(Stream input)
{
    string regexp = "xmlns=\".+?\"";
    string text;
    using (StreamReader reader = new StreamReader(input))
    {
        text = reader.ReadToEnd();
    }
    Regex expression = new Regex(regexp, RegexOptions.IgnoreCase|RegexOptions.Multiline);

    return expression.Replace(text, string.Empty);
}
