Sorting Sitecore data to multicolumn html table is quite hard in XSLT because data in XML is not sorted by item/@sortorder.
I finally found out how to do this so it will actually work and I am not loosing data. The trick is creating data first into a flat XML Nodeset and looping this data then to a multicolumn table using following-sibling::item commands. Here is the small sample code for this where I take abstract content structure from the Sitecore to a XML Nodeset <ul><li>xxxxxx</li></ul>.
First let’s make a variable.
<xsl:variable name=”keywords”>
<ul>
<xsl:for-each select=”$keywords”>
<xsl:for-each select=”descendant-or-self::item[(@template='keywords')]“>
<li>
<xsl:value-of select=”sc:fld(‘text’,.)”/>
</li>
</xsl:for-each>
</xsl:for-each>
</ul>
</xsl:variable>
Then using msxsl:node-set -function (http://msdn2.microsoft.com/en-us/library/hz88kef0(vs.71).aspx) I create nodeset out of the XSL variable and loop data to the html table.
<table>
<xsl:for-each select=”msxsl:node-set($keywords)/ul/li[position() mod 3 = 1]“>
<tr>
<td>
<xsl:value-of select=”.”/>
</td>
<xsl:for-each select=”following-sibling::li[position() < 3]“>
<td>
<xsl:value-of select=”.”/>
</td>
</xsl:for-each>
</tr>
</xsl:for-each>
</table>
I would be very keen to know if you have done this in pure XSLT because msxsl:node-set seems to be quite slow.
