From XmlDocument To XmlReader .Net

Question

After an advice from a user that answered to my question I'm tring to convert my XmlDocument code to XmlReader code but I'm having some troubles.

This is XML (generated from php-mysql Page)

<row>
<idLink>64</idLink>
<idHost>3</idHost>
<url>http://www.google.com</url>
</row>
<row>
<idLink>68</idLink>
<idHost>4</idHost>
<url>http://www.bing.com</url>
</row>
..... until about 10000 rows

This is my XmlDocument code:

   xmlDoc.Load("http://www.myUrl.com/list.php");
      if (xmlDoc.DocumentElement != null){
          foreach (XmlNode node in xmlDoc.DocumentElement)
             {
              if (node.Name == "row")
                {
                  list.Add(new Links { 
                       idLink = Convert.ToInt32(node.ChildNodes[0].InnerText),
                       idHost = Convert.ToInt32(node.ChildNodes[1].InnerText),
                       url = node.ChildNodes[2].InnerText }); 
                  }
             }  
             return list;

Now I have some trouble to Convert in XmlReader, I tried many code but I can't handle it.

using (XmlReader reader = new XmlTextReader("http://myUrl.com/list.php"))
         { 
          if (reader.NodeType == XmlNodeType.Element) 
           ?????

If you are doing read only operations on an xml file then you can you use XmlReader but as @Marc Gravell points out it is difficult.

In this situation I will create a class that wraps an XPathDocument using an XmlReader. I then create an XPathNavigator to read the data. Here's an example:

public class MyXmlReader
{
    public MyXmlReader(string xml)
    {
        StringReader sReader = new StringReader(xml);

        XPathDocument xml = new XPathDocument(XmlReader.Create(sReader));

        xmlNav = xml.CreateNavigator();
    }

    private XPathNavigator xmlNav = null;


    public MyDataModel ReadMyDataModel()
    {
        MyDataModel model = new MyDataModel();

        model.Read(xmlNav);

        return model;
    }
}

As shown above, the reading of the data can then be encapsulated into an associated object model. You can see some details in my answer on this question:
