That... sounds promising. As I write this I'm about to leave the house and head off to meet my co-developer and we'll give this a try. Thanks for your suggestion :)

Hi,


As far as I know xsl:key is a top-level element. But you can acchieve
what you want using something like:

<xsl:key name="playerResultLookupByWeek" match="playerResult"
use="concat(@player, '-', ../@week)" />

And using the same concat when calling this key..

Kind regards,
Geert

Interesting. It appears to work fine as it is for the first
iteration. The trouble with putting the key declaration
outside the template is that I would then not be able to
apply the [@week=$week] predicate to the match="playerResult"
which is what causes the lookup to be restricted to one of
the two sets of week data. How could I get around this, other
than hardcoding 2 keys, one for each week? I'd prefer not to
do that because if any new weeks are added to the XML then
they would not be included in the output.
