Re:  Fwd: Multiple OR Expression across a node-set
Thank you both very much for your suggestions, I'm looking into the
lookup table now.

Cheers,

Spencer

Spencer,

This is a classic case for a lookup table either in your XSLT or in a
separate document (where someone else might help to maintain it :-),
accessed via the document() function.

See http://www.dpawson.co.uk/xsl/sect2/N4995.html for some hints, or
search more broadly for "XSLT lookup tables".

The basic idea is that you construct a little XML that lists your
values; you then traverse this list instead of your input to do your
re-ordering. If you need to structure the list somehow, for example
to group the values (as your sample suggests you might), this is easy
enough to do (since it's XML). This also gives you a chance to
generate something special when values in your list are not
represented in your source file.

The code is more concise than the brute force method as well as
easier to maintain, since both your list of values and their order
are controlled as such, in one place.

I hope that helps,
Wendell
