Using RSS Feeds

I'm trying to use an rss feed on my asp.net website but can't get it to work. Here is the code behind the webpage:
    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        rssPosts.DataSource = GetRSSFeed("http://www.thepittsburghchannel.com/news/topstory.rss")
    End Sub

    Protected Function GetRSSFeed(ByVal strURL 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()
        Return ds.Tables(2)
    End Function

The result when I run this is an error: A column named 'category' already belongs to this DataTable: cannot set a nested table name to the same name.

I've tried many different rss feeds and all give the same result.

Any help would be greatly appreciated.

Hi stullhe104,
Perhaps you can use online Feed Validator to check the existing RSS file:

Thanks for the post. It does show that the rss feed is valid but that didn't help solve my problem.

I solved the problem by using RSSToolKit which I found at:
