I have the following script that retrieves the RSS feed from a site and displays it on my site.  I would like to limit the articles (rows) to 5.  Is this possible to limit the datatable rows?

Code:
  Sub Page_Load(sender as Object, e as EventArgs)    
    recentPosts.DataSource = GetRSSFeed("http://www.worthynews.com/news-editor/scripts/rss-news.php?nr=10")
    recentPosts.DataBind()      
  End Sub

  Function GetRSSFeed(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()
    ds.ReadXml(reader)    
    Return ds.Tables(3)
  End Function

you can't limit the rows in the table, but you can delete any extra rows

while ds.tables(3).Rows.Count >3
   ds.tables(3).Rows.RemoveAt(3)
end while
