Question

I am trying to read the data from XML File. In this elements are prefixed with ‘app’ and ‘gml’ text. because of these prefixes I am unable to read the data. For this I am trying to add namespace by using XMLNamespaceManager but not getting.

Edit:

        XmlDocument xmlDoc = new XmlDocument();
        xmlDoc.Load(new StringReader(strResult));
        NameTable nt = new NameTable();
        XmlNamespaceManager prefix = new XmlNamespaceManager(nt);
        string nmspc = xmlDoc.DocumentElement.NamespaceURI;
        prefix.AddNamespace("app:",xmlDoc.DocumentElement.NamespaceURI);

        prefix.PushScope();

Here the strResult contains XML Data

Something like:

var doc = new XmlDocument();
doc.Load(source);
var nsmgr = new XmlNamespaceManager(doc.NameTable);
nsmgr.AddNamespace("app", "http://www.weather.gov/forecasts/xml/OGC_services");
var firstPoint = doc.SelectSingleNode("//app:Forecast_Gml2Point", nsmgr);

Note that the namespace aliases are merely conveniences, and don’t have to match between the document and the namespace-manager – but it is probably easier if they do.
