I am using the cide below to check for a value in an xml file and would like to exit the loop if no match found and the last Receiver_ID element is checked, how do I modify my code to include the syntax for the last Receiver_ID element in my xml file? Or is there a way to obtain the totatal number of Receiver_ID in my file and use the count in my code, for example if count = 10 and Link_ID <> ""?

For Each xnLink As Xml.XmlNode In xdLink.SelectNodes("/Root/LinkA[Receiver_ID='" & C1Receiver.SelectedItem.Value & "']")
            Link_ID = xnLink.SelectSingleNode("LinkAID").InnerText
            If (positioned in Last Receiver_ID) and Link_ID <> ""
                Exit For
            End If
        Next

Thanks,
Victor

XmlTextReader reader = new XmlTextReader(sFileName);

i would rather suggest against using this approach, try to go for LINQ to XML.
Its much simpler and easy to use, here goes some examples:-
