Hi Allen,

It is hard to answer your question without knowing the input. In a subsequent post, please add a minimum working set of your data that applies to your stylesheet. In addition, it helps a great deal if you show exactly how the unwanted and the wanted output looks like (and I wouldn't object to indentation for readability in xml and xslt). I added some notes nevertheless, see below.

Cheers,

<xsl:call-template name="results"/>

Why did you choose to use call-template? Using apply-template and template matches is likely much easier.

<xsl:template name="results"> <table> <xsl:for-each select="insightResponse/searchResponse/collectionResultSet/object/thumbnail[position() mod 5 = 1]">

What this does highly depends on your input. For instance, if you have a set of "object" nodes, and each has one "thumbnail" node, then this for-each will select all of them (as postion() is always for each first thumbnail node under object). Depending on your input, you may want to write this a little different for readability, but as far as I can tell, this code is not wrong per se.

<tr> <xsl:apply-templates select=". | following-sibling::thumbnail[position() < 5]" />

This <tr> indeed will always show up, when you have at least one thumbnail in the xpath of the for-each. But I'm not certain I've understood your problem well enough. Next you apply the templates to the current thumbnail node and its first four siblings. Is this part working correctly?

</tr>
</xsl:for-each>
</table>
</xsl:template>
<xsl:template match="thumbnail"> <td align="center"><img src="{@URL}" /><br /> <xsl:for-each select="label"><xsl:value-of select="."/><br /></xsl:for-each> </td> </xsl:template>

Here you appear to output a bunch of values of label nodes. Is this part correctly working?
