Dear Friend,

Here what you can do is:-

Use System.XML namespace DOM classes getElementsByTagName method.

.....
System.Xml.XmlDocument doc = new System.Xml.XmlDocument();
doc.Load(@"c:\csnet\46\CSonsole\a1.xml");
System.Xml.XmlElement root = doc.DocumentElement;
System.Xml.XmlNodeList lst = root.GetElementsByTagName("id");

foreach (System.Xml.XmlNode n in lst)
{
Console.WriteLine(n.InnerText); // print id text
}

Try this :)

C#

using System;
using System.Data;

public partial class _Default : System.Web.UI.Page 
{
    DataSet ds = new DataSet();
    protected void Page_Load(object sender, EventArgs e)
    {
        if (Cache["Motos"] == null)
        {
            ds.ReadXml(Server.MapPath("~/XMLFiles/Motors.xml"), XmlReadMode.InferSchema);
            Cache.Insert("Motos", ds);
        }
        else
            ds = (DataSet)Cache["Motos"];
    }

    protected void drpMain_SelectedIndexChanged(object sender, EventArgs e)
    {
        System.Threading.Thread.Sleep(1200);

        if (drpMain.SelectedValue == "0")
        {
            drpMoto.Items.Clear();
            drpBrand.Items.Clear();
            drpMoto.Enabled = false;
            drpBrand.Enabled = false;
            btnGo.Enabled = false;
        }
        else if (drpMain.SelectedValue == "1")
        {
            drpMoto.DataTextField = "mcname";
