There's no sorting capability in XPath, sadly. You can do it in XSLT using
xsl:perform-sort, but it's still more lines of code than I would like,
unfortunately!

Subject: [xsl] Sorting distinct values
Hey,
Is there a way I overlooked in XPath to sort a sequence of numbers?
I'm pondering how to pull distinct values from a list, say
(0,3,17,4,6,4,3) and get them in sorted order.
distinct-values() in Saxon returns me (0,3,17,4,6) but I'd
like them as (0,3,4,6,17).
I did manage to do it in XSLT by grouping them by value,
sorting the groups, writing out the grouping keys and then
tokenizing the resulting string -- but that seems like a long
way to do it.
Any ideas for a spiffy short way?
Cheers,
Wendell
