Re: [xsl] maximum depth of nested tags needed for colspan

[Wendell Piez <wapiez@xxxxxxxxxxxxxxxx>]

Andy,

Mike's template (below) returns the maximum number of LINE elements under a 
set of nodes provided as the parameter $list.

You want the maximum depth of your question descendants.

One approach would simply be to pass in your set of question elements 
(//question) as the list, and change the expression "count($list[1]/line)" 
to "count($list[1]/ancestor-or-self::question)".

There are other ways to determine maxima, some of them quite elegant in 
their way ... if this doesn't work (guessing based on fragments of code is 
a little chancy sometimes), or if you need a more complete explanation of 
why it works the way it does, or if you want to see other approaches, ask 
again.

Cheers,
Wendell
