As said, for an element node you should check hasChildNodes() e.g.

XMLString = _
"<data><version>1.0</version><employee><employee_id></employee_id>" & _
   "<comments>freetext</comments></employee></data>"

Set XmlDocument = CreateObject("Msxml2.DOMDocument.3.0")
If XmlDocument.loadXML(XMLString) Then
   XmlDocument.setProperty "SelectionLanguage", "XPath"
   For Each Id In xmlDocument.selectNodes("//employee_id")
     If Not Id.hasChildNodes() Then
       Response.Write "id should not be empty"
     End If
   Next
Else
   Response.Write "parse error: " & xmlDocument.parseError.reason
End IF
