Subject: Re: recursive template call, howto

Charles,

Thank you, that gets me very close, except...

When I transformed the xml using the style sheet you provided, I got this:

   <table>
     <tr><td>1</td></tr>
     <tr><td>2</td></tr>
     <tr><td>7</td></tr>
     <tr><td>8</td></tr>
   </table>

   <table>
     <tr><td>3</td></tr>
     <tr><td>4</td></tr>
     <tr><td>5</td></tr>
     <tr><td>6</td></tr>
   </table>

The problem is that the two simple groups that came after the complex
group (lines 7 and 8) need to be in their own table after the complex
group, like this:

   <table>
     <tr><td>1</td></tr>
     <tr><td>2</td></tr>
   </table>

   <table>
     <tr><td>3</td></tr>
     <tr><td>4</td></tr>
     <tr><td>5</td></tr>
     <tr><td>6</td></tr>
   </table>

   <table>
     <tr><td>7</td></tr>
     <tr><td>8</td></tr>
   </table>

Subject:   recursive template call, howto

Here is the data:

<group>
  <line id = "1"/>
</group>
<group>
  <line id="2"/>
</group>
<group type="complex">
  <line id="3"/>
  <line id="4"/>
  <line id="5"/>
  <line id="6"/>
</group>
<group>
  <line id="7"/>
</group>
<group>
  <line id="8"/>
</group>

The idea behind the data is that there are two types of groups: simple
and complex.  The simple do not have a "type" attribute (it could if it
would help things).  The end result should be HTML where the first two
simple groups are in one HTML table, than there is a second table for
each of the complex groups and thing a final table for the last three
simple groups.  The order of simple and complex groups is random.

My thought was when the first simple group was encountered, call a
recursive template starting at the simple group and building a nodeset
of lines until a complex group or the end was encountered.  I cannot
figure out how to do that in xsl.  Am I on the right path? If so, how
do I do it?  If not, what is the right path?
