> Hi,

> I want to transform a list of items that can be of variable length into

> For example, the source list might have 40 items.  I therefore would want to

> Specifically, given a list of images, I want to create n pages with 6 images

> Question:  Is there a way to do this, or is this a limitation of XSLT?

On second glance, there's at least one bug in the above XSLT and it's hard 
to follow, so please disregard it.  Here's the pseudocode:


start a new page before
start table

for ( each Image item )
    if position mod 6 is 0
        add td item
        end row
        end table
        end page 
        start a new page before
        start table
    else if position mod 2 is 1
        start a new row
        add td item
    else if position mod 2 is 0
        add td item
        end row

end table
end page
