access to namespace prefix 2003-09-04 - By Mark Brucks
Jeff:
Finally getting around to saying thanks for the reply. I hadn't
carefully read the namespace parts of the XML documents, and assumed
that namespaces were not quite as flexible as they are (ie. I thought a
prefix/namespace pair were fixed for an entire document). Now I
understand why I was asking the wrong question.
Thanks - Mark
