Re: [xsl] Siblings to hierarchy: Better way to do this?

[Wendell Piez <wapiez@xxxxxxxxxxxxxxxx>]

Richard,

This is something of a FAQ, and DaveP has a writeup of some early answers 
to it at http://www.dpawson.co.uk/xsl/sect2/flatfile.html

The solution is basically what you have, but achieves your desiderata of 
speed and elegance by using keys.

And you asked:

Inside the predicate is not a test for node identity; it's a test for 
string equivalence, which isn't the same at all.

Keys are fun and easy once you get the hang of em.

Enjoy,
Wendell
