XML Document SelectNodes will not give results

 
When I tried to select nodes from the sample XML document shown below, I was not getting any results.
 
The reason is the "namespace".
 
When I select the nodes, I must use the right "namespace".
 
Here is the sample code which can add namespace first and then perform "SelectNodes" operation.
 
 
XmlDocument doc = new XmlDocument();
doc.Load(xmlFileName);
XmlNode docElement = doc.DocumentElement as XmlNode;
XmlNamespaceManager nsman = new XmlNamespaceManager(doc.NameTable);
nsman.AddNamespace("a", docElement.NamespaceURI);
XmlNodeList nodes = docElement.SelectNodes("a:Details/a:Section",nsman);

foreach (XmlNode node in nodes)
{
        // use node variable here.
}





Cheers
Happy Coding !
