Hi Vic,

Here's one solution to your problem:

With your source xml document (just above), 
the following transformation:
============================
<xsl:stylesheet version="1.0" 
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>

  <xsl:output method="html" indent="yes"/>
  
  <xsl:template match="/">
    <table>
      <xsl:apply-templates 
       select="/*/*/*/*[normalize-space()][position() mod 2 = 1]"
       mode="row"/>
    </table>
  </xsl:template>
  
  <xsl:template match="*" mode="row">
    <tr>
      <xsl:apply-templates select=". 
                                 | 
                                   following-sibling::*
                                              [normalize-space()][1]"/>
    </tr>
  </xsl:template>
  
  <xsl:template match="*">
    <td><xsl:value-of select="name()"/></td>
    <td><xsl:value-of select="."/></td>
  </xsl:template>
  
</xsl:stylesheet>

when applied produces the desired result:
========================================
<table>
   <tr>
      <td>d1</td>
      <td>one</td>
      <td>d4</td>
      <td>four</td>
   </tr>
   <tr>
      <td>d5</td>
      <td>five</td>
      <td>d6</td>
      <td>six</td>
   </tr>
   <tr>
      <td>d7</td>
      <td>seven</td>
      <td>d8</td>
      <td>eight</td>
   </tr>
   <tr>
      <td>d9</td>
      <td>nine</td>
      <td>d10</td>
      <td>ten</td>
   </tr>
</table>


Hope this helped.
