If the node id in an XML-Node doesn't exist the following code showed that oID is "nothing"

    'id
    Set oID = oUserdetails.selectSingleNode("id")
    id = oID.nodeTypedValue

So I tried only to assign value of oID to id when the node exists

    'id
    Set oID = oUserdetails.selectSingleNode("id")
    If oID <> Null Then
        id = oID.nodeTypedValue
    End If

But VB says that the object doesn't support this property "<> Null"

Thanks for any help

Hi Excattala,

You should test that the object IS Nothing:

If Not(oID Is Nothing) Then
  id = oID.NodeTypedValue
