是的，还有另一种方法，通过使用 XDocument类 [ ^ ]。

Yes, there is another way, via using XDocument class[^].

string sloc = "http://192.168.6.22/Conditions.aspx";

XDocument xdoc = XDocument.Load("fullfilename.xml");
XNamespace xnsp = "http://www.sitemaps.org/schemas/sitemap/0.9";

//return loc node - if exists
var qry = xdoc.Descendants(xnsp + "loc")
		.Where(a=>(string)a==sloc);

//or return boolean value (true/false)
//bool result = xdoc.Descendants(xnsp + "loc")
//		.Any(a=>(string)a==sloc);

如果你想使用XPath类获得结果，请参考：使用XPath导航选择节点 [ ^ ]



试试！
