delect topics with no children

I'm a newby-please be gentle. :) I import XML files into a map. This works beautifully. However, some of the elements in the XML contain no data, i.e. the XML element looks like <city></city> and appears in the map as a topic with no subtopics or data. See "City" below.

Does anyone know how to select all of these? Do I need a macro? Any suggestions on the macro? I've never written one for this program. Thanks very much!

Hello Jerry

A fun challenge... because it is probably more sophisticated than it first appears.

The following macro will select all the leaf nodes from (unfiltered) topics in the map.
'#Language "WWB-COM"
Option Explicit
Sub Main
Dim m_Topic As Topic
For Each m_Topic In ActiveDocument.Range(mmRangeAllTopics, False)
If m_Topic.AllSubTopics.Count = 0 Then
End If
End Sub

This works, but will select "GA" and "31210" in your example above, which might not be what you intended. It is easy to see visually that "City" and "Streename" are empty, but not quite so straightforward programmatically. You might need to add a term that only looks for childless topics that are also blue hexagons, or that have siblings with children.
