[REBOL] ANN: xml-object.r , and...a question about REBOL's built-in parse-xml
From: gavin::mckenzie::sympatico::ca at: 4-Oct-2001 22:45
Folks,
First, there's a new rev of xml-object.r (v 1.0.4) available at:
http://www3.sympatico.ca/gavin.mckenzie/
This release fixes an error with whitespace processing. And, I changed my
switch statements based on the recent switch/type? thread.
I've noticed some limitations in xml-object. If you have element with an
attribute and a subelement with the same name, bad things happen. This
should really be considered poor form in XML. However, it is legitimately
possible to encounter an attribute and subelement of the same local-name
within different namespaces.
I could also improve my mixed-content processing somewhat...anyway, more
work to do.
Now...on to a question.
I've been building some REBOL-Server-Pages where I query against a
MS-SQL-Server and get back an XML result set. So, I've been using the
built-in REBOL parse-xml rather than my parse-xml+ script, and I noticed
something that became very frustrating: when parse-xml encounters a XML
declaration (<?xml version ...?>) it calls a function...
check-version: func [version][print ["XML Version:" version]]
...which has the nasty side effect of printing out "XML Version" with the
version number.
This message, of course, messes up my carefully crafter HTML page that is
produced from my REBOL server page.
Anyway, my quick fix was to use my parse-xml+ function, but given that the
XML I was processing was tightly controlled and straightforward I was
actually expecting to stick to the built-in function. Oh well, I suppose I
could hack the build-in xml-language object that parse-xml uses and stub out
the check-version function, but that seems beside the point.
Has anyone else used parse-xml and considered this a real problem? I do
hope that some future rev of REBOL will drop the check-version print.
Gavin.
