(making balanced 2 columns)
They both flag errors when trying to test to see if they work at all.
I get the following error message when I run the following stuff in
XMLSpy
This file is not well-formed: & expected. Save anyway.
And it points to the location where the <= operator is present below in
the XSL.
Of course when I execute it flags Xpath errors in XMLSpy as well as
MSXSL 4.0
What seems to be the mistake in this example.
