In my project i added a timer that frequently checks a remote xml. What i want this new timer some how check if the rss feed is giving any result out. If it gives data out i for example reload webbrowser controle.IF it doesn't give any data out i do nothing. (I don't need to output xml content)Could any one show me how i can make such check.Thanks

Note:The url to check for its xml data is like this:
'http://localhost//datastatus.php?sessionkey=b429632c627bcf6bd4840561 690e3c49

Private Sub Form_Load()
     Timer2.Interval = 7000 ' <-- 10 seconds
    Timer2.Enabled = True
End Sub

Private Sub Timer2_Timer()
Static lngMin As Long

    lngMin = lngMin + 1
    'every 2nd timer tick reload the listview
    If lngMin Mod 2 Then
    End If

End Sub

Private Sub checkForNewData()
'Here i need to check for new data . If new data is avalible then
'reload the webbrowser.

'i need some how check if the following php code outputs any xml or not?

End Sub
