xml-dev - Illustration of Different Node Trees for XML (W3C(XT)/IE5)

["G. Ken Holman" <gkholman@CraneSoftwrights.com>]

I was asked to produce an IE5 version of my SHOWTREE free resource and I found
the results were interesting.  These reveal that alternate strategies are
required with different products when accessing components of an XML document
because the node structure interpreted by engines differ.

Versions of SHOWTREE for both W3C(XT) and IE5 are available through the
Resource Library link on our home page in my trailer below.

The stylesheets produce a text file from XT and an HTML file from IE5 ... one
can use the IE5 engine either directly viewing a file using an embedded
stylesheet processing instruction, or use the DOS command line if you want to
examine a file without changing it to include the PI (the command line
invocation is another free resource in the library).

I noted the following right away:

(1) XT instantiates text nodes for new lines between elements where IE5
doesn't
(2) XT regards the XML declaration as not being part of the content while IE5
does
(3) IE5 exposes the namespace declaration attributes as attributes while XT
doesn't
(4) XT composes node names using the namespace URI while IE5 doesn't

I haven't looked closely for other differences given some personal time
constraints.

I hope this is considered useful.
