I have tables with arbitrary columns and each cell can have an arbitrary number of paragraphs. I want to split rows on paragraphs, so each row only contains one <p> element.

Simplified input:

<table>

<tr>

<td>

<p>Para 1</p>

</td>

<td>

<p>Para 1</p>

<p>Para 2</p>

<p>Para 3</p>

</td>

<td>

<p>Para 1</p>

<p>Para 2</p>

</td>

</tr>

</table>

Desired output:

<table>

<tr>

<td>

<p>Para 1</p>

</td>

<td>

<p>Para 1</p>

</td>

<td>

<p>Para 1</p>

</td>

</tr>

<tr>

<td>

</td>

<td>

<p>Para 2</p>

</td>

<td>

<p>Para 2</p>

</td>

</tr>

<tr>

<td>

</td>

<td>

<p>Para 3</p>

</td>

<td>

</td>

</tr>

</table>

I am after suggestions as to the best way of tackling such a problem.

  <xsl:template match="tr">
      <xsl:variable name="this-row" select="."/>
      <xsl:for-each select="1 to max(td/count(p))">
          <tr>
              <xsl:apply-templates select="$this-row/*">
                  <xsl:with-param name="pos" select="."/>
              </xsl:apply-templates>
          </tr>
      </xsl:for-each>
  </xsl:template>

  <xsl:template match="td">
      <xsl:param name="pos"/>
      <xsl:copy>
          <xsl:apply-templates select="p[$pos]"/>
      </xsl:copy>
  </xsl:template>
