I tried as above but i am getting null vaule in node list

C#

XmlNodeList xnList = doc.SelectNodes("/Locations");
      foreach (XmlNode xn in xnList)
      {
          XmlNode anode = doc.SelectSingleNode(string.Format( "North"));
          if (anode != null)
          {
              XmlNodeList CNodes = xn.SelectNodes("DHI/METRO/DETAILS/CItyname");
              foreach (XmlNode node in CNodes)
              {
                  XmlNode example = node.SelectSingleNode("cityid");
                  if (example != null)
                  {
                      string na = example.InnerText;

Is the structure fixed? That is, do you always have CityName at the end of same list of node paths?

If so, just use //CityName in SelectNodes - it will return nodes CityName wherever they are in the document.

Other then that, you use String.Format without formatting (in the second example string.Format("North") in the first
String.Format(long concatenation) in the other example

Try instead:

C#

String.Format("/{0}/{1}/{2}/{3}/DETAILS", "Locations", Session["North"], Session["DHI"], Session["METRO"])

Also note that XML is case sensitive in searches...so check that North shouldn't be NORTH or something like that.

In the first example you have missed the level CItyname and you are not using string.Format correctly.

In the second attempt you are attempting to select nodes from the wrong objects in the following lines:

C#

XmlNode anode = doc.SelectSingleNode(string.Format( "North"));

should be

C#

XmlNode anode = xn.SelectSingleNode("North");

(no need for the string.format) and similarly

XmlNodeList CNodes = xn.SelectNodes("DHI/METRO/DETAILS/CItyname");
