Re: [xsl] Nested grouping using group-starting-with - brief code review?

["Imsieke, Gerrit, le-tex" <gerrit.imsieke@xxxxxxxxx>]

Dear Peter,

For just 2 levels of nested grouping, your approach seems reasonable. A 
more generic approach using recursive grouping (and permitting gaps in 
hierarchy, for example h3 following h1) may be found here:
http://www.biglist.com/lists/lists.mulberrytech.com/xsl-list/archives/201004/msg00124.html
Since this was meant for ToC generation, you'll have to replace all the 
<ul> stuff with <section> as appropriate, and remove the comment on the 
line below "<!-- no output for non-headings, as we are creating the ToC: 
-->".

Hope this helps.

Gerrit
