Subject: RE: RE: [xsl] Selecting the first node set From: Wendell Piez <wapiez@xxxxxxxxxxxxxxxx> Date: Tue, 15 Aug 2006 14:22:57 0400 
I find it easier to think of things visually (I always did well in geometry but stumbled in algebra). What we're really working with is the notion of sets, so I think of a Venn diagram. I picture this:
"x  y[1]"
as "The set of all xthings and the first ything."
and this:
"(x  y)[1]"
as "The first element of the set of all xthings and all ythings."
Is that about right?
Cheers, Wendell
