Re: Splitting merged XHTML cells

Long time ago I solved this problem. And I cheated: I used JavaScript embeded 
into XSLT (using
MSXML) so I reconstructed the table into a grid.

I need to transform xhtml table to special output. Its syntax for merging
cells is similar to xhtml, but it requires to specify every cell even if it
is merged:

<tr>
  <td rowspan="2" colspan="2">A1:B2</td>
  <td>C1</td>
</tr>
<tr>
  <td>C2</td>
</tr>

<RowStart:><CellStart:2,2>A1:B1<CellEnd:><CellStart:1,1><CellEnd:><CellStart
:1,1>C1<CellEnd:><RowEnd:>
<RowStart:><CellStart:1,1><CellEnd:><CellStart:1,1><CellEnd:><CellStart:1,1>
C2<CellEnd:><RowEnd:>

For colspan I use recursion and it works fine, but for rowspan and
combination with colspan I have no idea:

<xsl:template match="xhtml:table">
  ...
  <xsl:for-each select="xhtml:tr">
    <xsl:text>&lt;RowStart:&gt;</xsl:text>
    <xsl:for-each select="./xhtml:td">
      <xsl:call-template name="addTableCells">
      <xsl:with-param name="numRows" select="./@rowspan" />
      <xsl:with-param name="numCols" select="./@colspan" />
      <xsl:with-param name="content" select="." />
      </xsl:call-template>
    </xsl:for-each>
    <xsl:text>&lt;RowEnd:&gt;</xsl:text>
  </xsl:for-each>
</xsl:template>

<xsl:template name="addTableCells">
  <xsl:param name="numRows" select="1" />
  <xsl:param name="numCols" select="1" />
  <xsl:param name="content" />
  <xsl:text>&lt;CellStart:</xsl:text>
  <!-- rowspan -->
  <xsl:value-of select="$numRows" />
  <xsl:text>,</xsl:text>
  <!-- colspan -->
  <xsl:value-of select="$numCols" />
  <xsl:text>&gt;</xsl:text>
  <xsl:value-of select="$content" />
  <xsl:text>&lt;CellEnd:&gt;</xsl:text>
  <!-- if columns are spanned -->
  <xsl:if test="$numCols &gt; 1">
    <xsl:call-template name="addTableCells">
    <xsl:with-param name="numRows" select="1" />
    <xsl:with-param name="numCols" select="$numCols - 1" />
    </xsl:call-template>
  </xsl:if>
</xsl:template>

I thing similar problem was discussed here:

without proper solution.
