Extending DataForm Web part Not showing Node Value

Question

I'm trying to create a custom web part by inheriting the dataformwebpart. the problem i'm facing is that in xsl i'm not able to display value of xml nodes although i'm getting the names of nodes.

below is my sample code, xsl, xml

 public override void DataBind()
    {

      XmlDocument doc = GetFeedsXML(); 
      XmlDataSource source = new XmlDataSource();
      source.ID = "wallXML";
      source.Data = doc.InnerXml;
      this.DataSource = source;
      base.Xsl = this.Xsl;
      base.DataBind();

    }

XSL

Answer 1

I found the answer for the same i had to override one more method

protected override XPathNavigator GetXPathNavigator(string viewPath)

        {

            return doc.CreateNavigator();

        }
