I am trying to create an ASP.NET application that
consumes an RSS Newsfeed from Yahoo News
(http://rss.news.yahoo.com/rss/topstories). I keep
getting the following error message, even though my code
seems corect. In fact, when I drop virtually the same
code into a Windows Forms application using VB.NET and
use a Windows Forms datagrid, I get the xml from the
newsfeed without any problem.
Here is the error message:
"The 'META' start tag on line '1' doesn't match the end
tag of 'HEAD' in file
http://rss.news.yahoo. com/rss/topstories'. Line 1,
position 135."
Here is my code from my ASPX page:
<%@ Import Namespace="Syst em.Data" %>
<%@ Import Namespace="Syst em.Xml" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0
Transitional//EN">
<HTML>

Private Const YAHOO_RSS_FEED As String
= "http://rss.news.yahoo. com/rss/topstories"
Sub Page_Load(sende r as Object, e as EventArgs)
'Cache the top stories for 20 minutes
If Cache("YahooTop Stories") Is Nothing then
'Item not in cache, get it manually
Dim dt as DataTable = GetRSSFeed(YAHO O_RSS_FEED)
Cache.Insert("Y ahooTopStories" , dt, Nothing,

End If
topStories.Data Source = Cache("YahooTop Stories")

End Sub
Function GetRSSFeed(strU RL as String) as DataTable
'Get the XML data
Dim reader as XmlTextReader = New XmlTextReader
(strURL)
'return a new DataSet
Dim ds as DataSet = New DataSet()
ds.ReadXml(read er)
Return ds.Tables(2)
End Function
</script>

Do you know what I need to change?
Thanks in advance.
