Each news record has a "release date" value. I am not sure
of the format but
hopefully my code could handle multiple formats, or if there
is a standard for
date formatting in XML maybe the CMS uses that.
I would recommend working with the ISO 8601 format which is also used by XML
Schema - this will maximize the chances for interoperability. This is
YYYY-MM-DD.
It's simplest to pass the date to the stylesheet as a parameter. If you
can't do that, another approach is to access it using the document()
function with a URL such as local://date which you intercept in an
XmlResolver, returning an XML document containing the current date.
For date arithmetic, e.g. calculating the date 5 days from now, look at the
EXSLT library at www.exslt.org
Of course it all gets easier with XSLT 2.0 but you appear to have given
yourself platform constraints.

On a main
page I need to list
the latest 5 article titles based on this "release date",
with links to the
article content. That would seem like a simple sort with
some kind of break
condition after 5 loops (though I'm not even sure how to do
that), but the
complication is that each record also has a "highlight until"
date; if the
current system date is before the "highlight until" date,
those highlighted
records need to appear at the top of the list, which should still be
constrained to 5 articles.
It seems that XSL doesn't inherently know what date it is, so
either my CMS
vendor should already be passing that or I need to figure out
how to pass this
as a parameter to my XSL. I'm also not finding many web
references to this
specific kind of date logic. Based on these I'm wondering if
a .NET component
is the right way to go, but since the data is already in XML
I think I would
prefer XSL if possible/not too complicated.
Any assistance would be greatly appreciated.
Thanks,
-John
