Hi,

This error occurs in your situation because on of the objects you're creating is not being created properly. Step through the code with a breakpoint and just hover the mouse over the objects to see which ones are nothing. This line grabs my attention:

Set xmlDataListTag = xmlDoc.getElementsByTagName("Exception")

Firstly, does the node "Exception" exist? If it does, xml is case sensitive, so is it called EXCEPTION, exception, eXcepTion, etc.? If it does exist, does it return anything to xmlDataListTag? It's difficult to give much help without seeing more of the code.

Regards,

Lee

>>Set itX = xmlDataListTag.NextNode
here xmlDataListTag.NextNode returns blank to the itX

Try some extra handling
   
    Set itX = xmlDataListTag.nextNode
    If itX Is Nothing Then
        MsgBox "Node not found"
        Exit Sub ' or Exit Function
    End If

Is there a valid element called "MainCode" in the itX object?

If so, is it actually spelled as MainCode or is it in all lowercase or uppercase?
