I think i get a problem with the union operator then, as the xalan server 
the translation is running on can't seem to cope with more than 27 unions of 
files in a for-each statement (it doesnt seem to have enough memory).

I am assuming when u say "><xsl:for-each select="some path that selects at 
least one node from each
document">
 ... select="key(..."
it would be something like <xsl:for-each 
select="document($nsindex/filename)/root/link | 
document($nsindex/filename)/root/link | 
document($nsindex/filename)/root/link">? as i tried something like this 
earlier and placed an xsl:sort after, this is when i encountered the union 
problem!



I forgot to say i have about 30 files which need to be searched.

you can't have a single key lookup that covers more than one document.
xsl:key applies to all documents but each is indexed separately and
key() just returns nodes from the current document.

so you need to go
<xsl:for-each select="some path that selects at least one node from each
document">
 ... select="key(...

Often this isn't quite the semantic that you want, but it's the semantic
that you get:-)
