We need to see your XML and need to know what obj is, what i is.
The data property makes sense on text nodes or cdata section nodes and 
empty text nodes might not even be included in the DOM tree.
For an element node you can simply check e.g.
   If obj.hasChildNodes() Then
     ' obj is not empty
   Else
     ' obj is empty
   End If

Example

Set xmlDocument = CreateObject("Msxml2.DOMDocument.3.0")
xmlDocument.loadXML "<gods><god>Kibo</god><god /></gods>"
For Each god in xmlDocument.documentElement.childNodes
   If god.hasChildNodes() Then
     WScript.Echo "Node is not empty."
   Else
     WScript.Echo "Node is empty."
   End If
Next
