Re: mod position() tests positive all of the time

Thanks everyone for their input.  I'm still having the same counting
problem after working with some of the suggestions.  I have worked
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:

<insightResponse>

For the transformation I am thinking, There will be only 1 thumbnail
for each object.  Ideally, I would like to get:

<table>
<tr><td align="center"><img src="http://somelink">< br />labels<br
/></td><td>repeat sequence 4 more times</td></tr>
<tr>five more cells</tr></table>

I am using Chuck Knell's suggestion of a stylesheet, but I am getting
the same result.
