This is true and I'm a huge fan of sibling recursion, but Mike's first suggestion will handle this as well.

That is, if the results of your grouping operation are bound to a variable, you can then process these results to group your groups by position or whatever.

Of course this is a micropipeline.

Cheers,

Hi everybody,

is there a way to limit the number of groups that are constructed by
<xsl:for-each-group>?


XML: <line> v <tab /> w <tab /> x <tab /> y <tab/> z <line>

(v, w, x, y, z being mixed data)


In the example above, <xsl:for-each-group select="node()" group-ending-with="tab"> will find 5 groups.

Let's say I want no more than 3 groups, where the third group contains
"all the rest":
(1) v <tab />
(2) w <tab />
(3) x <tab /> y <tab/> z

To be more precise:
Groups 1 and 2 shall be processed on their own,
Groups 3 and all following groups shall go together in further
processing.



Thanks for your answers,
Norbert
