Re: Splitting data into smaller groups for HTML output

Thanks Wendell,

The way I'm looking to split the items into groups is as follows.

1 to 5 items - 1 group
6 to 10 items - 2 groups
11 to 15 items - 3 groups
16 - 20 items - 4 groups
21 - 25 items - 5 groups

So the number of groups will in fact depend on the number of <source>
nodes in the XML file. The <source> nodes will are already in the
correct order in the XML file so I don't need to sort them in any
other way in the XSL.

Cheers,
Mike.
