Re: [xsl] Process an element depending...

[Peter Davis <pdavis152 at attbi dot com>]

You pretty much have two courses of action:

(1) A tag contains four nw, sw, ne, or se tags
(2) it contains text or something else

In the case of (1), you need to output a table with two rows and two columns, 
which means one cell per quadrant.  In each of the cells, apply-templates 
with the tag that goes in that quadrant.

In the case of (2), there are two additional choices:

(2a) if there is anything inside the tag (other tags or non-whitespace text), 
then apply-templates on that content.  
(2b) Otherwise, output a <br/> or &#160; to make the HTML table happy.

It's actually not that difficult.  You just need an <xsl:choose> with those 
three choices as the <xsl:when> tests.  The code below assumes that the only 
elements that contain nw|sw|ne|se are other nw|sw|ne|se tags or the root 
document; you should change the template to match all of the elements that 
can contain or be contained in nw|sw|ne|se (or just make it match="node()" to 
be lazy).

<xsl:template match="/ | nw | sw | ne | se">
  <!-- untested -->
  <xsl:choose>
    <xsl:when test="nw or sw or ne or se">
      <table width="100%">
        <tr>
          <td width="50%">
            <xsl:apply-templates select="nw"/>
          </td>
          <td width="50%">
            <xsl:apply-templates select="nw"/>
          </td>
        </tr>
        <tr>
          <td width="50%">
            <xsl:apply-templates select="sw"/>
          </td>
          <td width="50%">
            <xsl:apply-templates select="se"/>
          </td>
        </tr>
      </table>
    </xsl:when>
    <xsl:when test="child::* or normalize-space(.)">
      <xsl:apply-templates/>
    </xsl:when>    
    <xsl:otherwise>
<!-- Another option is to just put <br/> at the end of each <td> above, 
remove the second <xsl:when>, and change the <br/> here to 
<xsl:apply-templates/>.  This will make it always output the <br/> in every 
<td>, but it is a little easier to generalize if this is not your only 
template. -->
      <br/>
    </xsl:otherwise>
  </xsl:choose>
</xsl:template>
