Question

XDocument coordinates = XDocument.Load("http://feeds.feedburner.com/TechCrunch");
System.IO.StreamWriter StreamWriter1 = new System.IO.StreamWriter(DestFile);
XNamespace nsContent = "http://purl.org/rss/1.0/modules/content/";
string pchild = null;

foreach (var item in coordinates.Descendants("item"))
{
   string link = item.Element("guid").Value;

   //string content = item.Element(nsContent + "encoded").Value;
   foreach (var child in item.Descendants(nsContent + "encoded"))
   {
      pchild = pchild + child.Element("p").Value;
   }

   StreamWriter1.WriteLine(link + Environment.NewLine +  Environment.NewLine + pchild + Environment.NewLine);
}

StreamWriter1.Close();

If i use Commented line code (string content = item.Element(nsContent + "encoded").Value;) instead of inner for loop than it will fetch the value of <conten:encoded> element but it contains all links, images etc etc. And I want only text.

For that I have tried to use this filter (inner for loop) but its showing error :

Object reference not set to an instance of an object.

Please suggest me code so that I can store only text and remove all other links, <img> tags etc.

The content of item.Element(nsContent + "encoded").Value is html not xml. You should parse it accordingly, such as using Html Agility Pack

See the example below

string content = item.Element(nsContent + "encoded").Value;
HtmlAgilityPack.HtmlDocument doc = new HtmlAgilityPack.HtmlDocument();
doc.Load(new StringReader(content));
var text = String.Join(Environment.NewLine + Environment.NewLine,
                doc.DocumentNode
                .Descendants("p")
                .Select(n => "\t" + System.Web.HttpUtility.HtmlDecode(n.InnerText))
            );
