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

C#

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);

If you want to get result using XPath class, please refer this: Select Nodes Using XPath Navigation[^]

Try!
