RE: [xsl] Can not convert number to a NodeList

["Aron Bock" <aronbock@xxxxxxxxxxx>]

Carlos,

I believe the prior respondent mentioned 2 ways to achieve what you want: 
recursively write out rows and col or, if using for-each, supply for the 
"rows" a nodeset equal to the number of @lines.  The second approach is 
described below (and for simplicity we derive # cols ):

With this input:

<data>
   <radio line="1">
       <opt>Masc</opt>
       <opt>Fem</opt>
       <opt>other</opt>
       <opt>Masc2</opt>
       <opt>Fem2</opt>
       <opt>other2</opt>
   </radio>
</data>

This XSL:

<?xml version="1.0" encoding="iso8859-1"?>
<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
   <xsl:output method="xml" indent="yes"/>
   <xsl:strip-space elements="*"/>

   <xsl:template match="radio">
       <table>
           <xsl:variable name="numcols" select="count(opt) div @line"/>
           <xsl:for-each select="opt[position() &lt;= current()/@line]">
               <xsl:variable name="r" select="position() - 1"/>
               <tr>
                   <xsl:apply-templates select="../opt[position() &gt;= $r 
* $numcols + 1
                       and position() &lt;= $r * $numcols + $numcols ]"/>
               </tr>
           </xsl:for-each>
       </table>
   </xsl:template>

   <xsl:template match="opt">
       <td><xsl:value-of select="."/></td>
   </xsl:template>

</xsl:stylesheet>


produces:

<?xml version="1.0" encoding="UTF-8"?>
<table>
 <tr>
   <td>Masc</td>
   <td>Fem</td>
   <td>other</td>
   <td>Masc2</td>
   <td>Fem2</td>
   <td>other2</td>
 </tr>
</table>

If you change @lines to 2, you should get 2 rows.

This may not work for @lines = sqrt( 2 )
