I'm still having the same counting

mainly with Abel's and Chuck Knell's suggestion, and I'm getting the
same results.  This is output that comes from an XML gateway into a
PHP/Sablotron script for formatting.

As per Abel's suggection, the input xml data I am using is included in
the post:

Thanks for your input. That clarifies a lot. Others have already pointed out the difference between the siblings and cousins of object and thumbnail nodes. Here's a solution that works with your input, using only templates and no xsl:for-each (push model) or xsl:choose (often, an xsl:choose can be replaced by a template rule). It's largely a matter of taste which solution you want to use.

Because the thumbnail node lying inside the object node, the need for a separated mode has gone. Basically, the whole template becomes easier and more straightforward. I upgraded it to work with your input. A side effect of the chosen xpaths is that it also works with a structure that has more than one thumbnail inside an object node. I added some comments for clarification.

Consider placing "5" (your mod value) in a global variable. That will ease modification later on. Putting it in a parameter will make it configurable from the processor (if you can set parameters, that is).

HtH,
