 Refer below snippet:
             
                       string sContent = File.ReadAllText(xmlfile);
                        StringReader DocumentReader = new StringReader(sContent);
                        XmlDocument xmlDoc = new XmlDocument();
                        xmlDoc.Load(DocumentReader);
                        ReferenceNodes = xmlDoc.GetElementsByTagName("content:Topic");
                       
                        foreach (XmlNode Node in ReferenceNodes)
                        {
                            if (Node.Attributes["TopicName"] != null)
                            {
                                string sTopicName = Node.Attributes["TopicName"].Value;
                            }
                        }

If you like LINQ here is another bit of code you can play with:


 
string filePath = HttpContext.Current.Server.MapPath(SettingsModel.XMLFileLocation + "MyXML.xml");
            if (File.Exists(filePath))
            {
                var xml = (from x in XElement.Load(filePath).Elements("MyXML") 
                           select new XMLModel
                           {
                               ID = x.Element("ID").Value,
                               Value = x.Element("Value").Value
                           });
                return xml;
            }

Hi nisarkhan;

The following Linq to XML quesry will do what you need.

public void LoadXML( )
{
    XElement xdoc = XElement.Load( "C:/Working Directory/Catalog.xml" );
    XNamespace content = "sitename.xsd";

    var topics = ( from t in xdoc.Descendants( content + "Topic" )
                   select t.Attribute( "TopicName" ).Value ).Distinct( );

    foreach (string topic in topics)
    {
        DropDownList1.Items.Add(topic);                
    }
}
