simple xml parsing

what is the simplest way to parse the lat and long out of the following xml fragment. There is no namespace etc.

It is in a string variable. not a stream.

<poi>
      <city>stockholm</city>
      <country>sweden</country>
      <gpoint>
        <lat>51.1</lat>
        <lng>67.98</lng>
      </gpoint>
</poi>

everything I have read so far is waaaaay too complex for what should be a simple task e.g. Link

I've been looking at the above link

Surely there is a simpler way to do this in .net?

using System.IO;
using System.Xml;
using System.Xml.XPath;

. . .

    string xml = @"<poi>      
                     <city>stockholm</city>  
                     <country>sweden</countr>
                        <gpoint>        
                            <lat>51.1</lat>        
                            <lng>67.98</lng>    
                        </gpoint>
                   </poi>";

    XmlReaderSettings set = new XmlReaderSettings();
    set.ConformanceLevel = ConformanceLevel.Fragment;

    XPathDocument doc = 
        new XPathDocument(XmlReader.Create(new StringReader(xml), set));

    XPathNavigator nav = doc.CreateNavigator();


    Console.WriteLine(nav.SelectSingleNode("/poi/gpoint/lat"));
    Console.WriteLine(nav.SelectSingleNode("/poi/gpoint/lng"));

You could of course use xpath SelectSingleNode to select the <gpoint> element into a variable.
