[xsl] sorting product descriptions

[Tobias Reif <tobiasreif at yahoo dot com>]

Hi all;

I need to sort a list of product-descriptions, in the
form

<products>
	<product id="a_a_00_03">
		...content...
	</product>
...........
</products>

The "id"s can take the form
a_a_00_00 or a_a_90_30_20 or even a_b_100_30

I wrote a horrific sorting thing
http://www.pinkjuice.com/temp/XSLT/sort-products/
which works only with 2 pairs of digits, is very
verbose and slow, and seems to be unable to deal with
"id"s that don't form a sequence.
(it generates a sequence of "id"s, and outputs any
item that has the same; if there are only two items to
sort, but their numbers are different by thousands,
this thing would probably take 10 minutes to sort two
items ;) )

I would be interested in the shortest, simplest,
fastest way to deal with this ;)

Is this possible in XSLT?
(("bubble-sort"?:)go through all items; check pairs
consisting the current one and the following one: if
they are in the correct order, leave them, if they are
placed the wrong way round, switch them. stop as soon
as there's nothing left to swith.)
