1 file like xmlns="
Example XML file:
<?xml version="1.0" encoding="UTF-8"?>
<WebSrvMessage xmlns="http://www.lenoval.com/">
  <version>1.0</version>
  <DataContent>
<DateTag>2010-5-17</DateTag>
  </DataContent>
</WebSrvMessage>

XmlDocument doc = new XmlDocument();
doc. Load(path);
XmlNamespaceManager nsmgr = new XmlNamespaceManager(doc. NameTable);
Add a namespace, and the prefix can be named at will
nsmgr. AddNamespace("lvl", "http://www.lenoval.com/");

//在路径前面使用前面定义的前缀
XmlNode datatag = doc. DocumentElement.SelectSingleNode("lvl:QryDataContent/lvl:DateTag", nsmgr);

2 Files like xmlns:xxxx="
For example: xmlns:lenoval="http://www.lenoval.com/">
You can add a namespace to the code above:
Add a namespace, and the prefix can be named at will
nsmgr. AddNamespace("lenoval", "http://www.lenoval.com/");

//在路径前面使用前面定义的前缀
XmlNode datatag = doc. DocumentElement.SelectSingleNode("lenoval:QryDataContent/lenoval:DateTag", nsmgr);

/// <summary>
/// 读取网站地图xml
/// </summary>
/// <param name="code"></param>
/// <returns></returns>
public static List<string> GetUrl(string code)
{
List<string> list = new List<string>();
XmlDocument d = new XmlDocument();
d.Load(code);
XmlNamespaceManager m = new XmlNamespaceManager(d.NameTable);
m.AddNamespace("x", "http://www.sitemaps.org/schemas/sitemap/0.9");
XmlNodeList url = d.SelectNodes("//x:url", m);
foreach (XmlNode nd in url)
{
XmlNode loc = nd.SelectSingleNode("x:loc", m);
list.Add(loc.InnerText);
}
return list;
}
