RE: Grouping question [1.0 way]

Hmmm.  Well, this works with XSLT 1.0

<xsl:key name="color-group" match="n" use="@color"/>

<xsl:template match="/">
 <tables>
  <xsl:for-each
select="/data/n[generate-id()=generate-id(key('color-group',@color)[1])]">
   <xsl:sort select="." />
   <table>
    <xsl:for-each select="key('color-group',@color)">
     <xsl:if test="position() mod 2">
      <xsl:variable name="color" select="@color" />
      <tr>
       <td>
        <xsl:value-of select="." />
       </td>
       <xsl:if
test="following-sibling::n[@color=$color]">
        <td>
         <xsl:value-of
select="following-sibling::n[@color=$color]" />
        </td>
       </xsl:if>
      </tr>
     </xsl:if>
    </xsl:for-each>
   </table>
  </xsl:for-each>
 </tables>
</xsl:template>
