Cleaning up superfluous text boxes

[Jay Sclar]

I have about 100 Visio network diagrams I would like to
clean up. Previous authors have left a lot of extra unused
text boxes on the drawings which make it difficult to
select only the "real" text boxes which include text.
Besides being sloppy, these extra boxes somewhat increase
the file sizes of the drawings. Unfortunately, the unused
text boxes are about in the same positions as the used ones.

Is there any simple way to find text boxes which have null
text in them so as to easily delete them?

Many TIA

Graham Wideman made an interesting observation in his book
about exporting to xml and then using a text editor to
clean up repetitive types of mistakes.
