Re: [xsl] Flat to Structured: Handling List Items with Subordinate Paragraphs

[Wendell Piez <wapiez@xxxxxxxxxxxxxxxx>]

Hi Eliot,

Yeah, sibling recursion was something we had to resort to before we 
had native grouping constructs, to allow XSLT to see structural 
relations where it only had contiguity.

These days, grouping-based solutions using group-adjacent, 
group-starting-with and group-ending-with are available; they are 
much easier to get one's head around and much much easier to 
abstract, generalize, encapsulate and maintain, which you are very 
much likely to want.

As a consequence, sibling recursion of the classic sort is hardly 
necessary in XSLT 2.0. Structural induction becomes a special kind of 
grouping problem.

Cheers,
Wendell
