Re: [xsl] List grouping

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

Ibd tackle it like this:

In a template that matches *[w:p], do an adjacent grouping of * with the 
key exists(w:pPr/w:listPr/w:ilvl/@w:val).

Then choose: when not(current-grouping-key()), pass the group unchanged. 
If current-grouping-key(), call a template or a function that youbll 
call recursively later on.

As xsl:param $elements, it takes the current-group().

First it calculates a variable $min as the min() of 
$elements/w:pPr/w:listPr/w:ilvl/@w:val (you might need to cast them as 
xs:double before applying min()).

Then it opens a list element. Within it, it groups the $elements, 
group-starting-with="*[number(w:pPr/w:listPr/w:ilvl/@w:val) = $min]".

Then a fringe case can happen: the first list items w:ilvl/@w:val is 
larger than $min. This means that the list starts with a 2nd-level 'a.' 
instead of a first-level '1.'. You can decide to handle this case, or 
you may just flag this as an input error.

In the normal case that each group indeed starts with the same level, 
create an li element, put the current-group()'s number and first and 
content in.

If there are more elements in the current-group(), call the template or 
the function on them, with elements = current-group()[position gt 1].

I hope it performs as expected and I didnbt put a mistake in. Writing 
and testing the actual XSLT code would probably have taken less time, 
but maybe itbs better for didactic reasons if you figure out the actual 
code yourself.
