Hi David,

I understand how to select the elements with not(text()) and to use an
Xpath expression to make a new row every
four items, but I do not see how to select a run of content-less
elements that need to be treated that way.
This is a pattern I've been using myself lately, to generate labels
(effectively, same problem):
<xsl:template name="rowsof4">
<xsl:param name="nodes" select="/self::*"/>
<!-- the default is a fancy way of saying 'no nodes'
(by asking for the root node that is an element) -->
<xsl:for-each select="$nodes">
<xsl:variable name="node-position" select="position()"/>
<xsl:if test="$node-position mod 4 = 1">
<tr>
<xsl:apply-templates mode="cell"
select=". | $nodes[$node-position + 1]
| $nodes[$node-position + 2]
| $nodes[$node-position + 3]"/>
</tr>
</xsl:for-each>
</xsl:template>
then...
<xsl:call-template name="rowsof4">
<xsl:with-param name="nodes" select="$the-elements-you-want-in-your-rows]"/>
</xsl:call-template>
... leaving the rest (e.g. the "cell" mode) for you to fill in.
If you wanted to parameterize the rows template so it could build a row of
any number of cells (passed in as another parameter) -- that could be done.
Note that this doesn't fill in "empty" cells when your set falls short (not
necessary for my labels app) ... that could be added too.
I hope this helps!
Cheers,
Wendell
