RE: [xsl] building a nodeset from selected nodes

["Hall, Kurt" <khall@xxxxxxxxxxx>]

Hi Wendell,

Using key() is sooooo much easier than recursive templates.

I originally thought of doing this (assuming I understand you) but 
then I got back to the problem where I have multiple node-sets with 
no obvious (to me?) way to combine them into a single node-set, though 
I was eventually able to combine them using recursive template calls.  
Is there a simpler approach to combine a variable number of node-sets
into a single node-set (without using extensions)?

Thanks again,
-kurt

Hi Kurt,

I see you've picked up the nice feature that that second argument can 
return a node-set and not be treated as a string.

(Even if it didn't, you could still iterate over the column children and 
use . for that second argument. ;-)

But as I said, we use keys so much for grouping, we forget the general case 
of what they're really for, "a way to work with documents that contain an 
implicit cross-reference structure" [XSLT 12].

Cheers,
Wendell
