I have checked the RSS feed you gave. They are having nodes classifying it as IPL. And scanning for IPl keyword may not give you correct results. Think of some other feed which this type of classification

You haven't missed any thing. There is no node.

Intereting question: filtering XML by a substring in a CDATA...

See http://stackoverflow.com/questions/568315/how-do-i-retrieve-element-text-inside-cdata-markup-via-xpath[^] to get the contents of a CDATA in a XPath query.
You may need an XPath query like //item[fn:contains(/description/InnerText(),"IPL")]
(not tested).

More on 'contains': http://www.w3schools.com/xpath/xpath_functions.asp[^]

Hope this helps,

Thanks ,

I have tried like following
<asp:XmlDataSource ID="XmlDataSource1" runat="server" DataFile="http://www.indiatvnews.com/rssfeed/sports_cricket_news.php"
XPath="/item[fn:contains(/description/InnerText(),'IPL')]">

but it gives exception
System.Xml.XPath.XPathException: 'rss/channel/item[fn:contains(/description/InnerText(),'IPL')]' has an invalid token.

please help me.

Thanks again

Off the top of my head, I can suggest two things:
1. Start your query with a double slash: XPath="//item.. insted of XPath="/item
2. Try debugging the XPATH part by part:

XPath="//item/description"
XPath="//item/description/InnerText()"
XPath="//item/description/[fn:contains(InnerText(),'IPL')]"
XPath="//item[fn:contains(/description/InnerText(),'IPL')]"
XPath="fn:contains(//item/description/InnerText(),'IPL')"

I'm a little rusty about how fn:contains works, and which namespaces you should import.
When you get it to work, please share the query!

Hope this helps,
Pablo.
