Re: [xsl] variable outside a for-each loop: second try

["Mathieu Malaterre" <mathieu.malaterre@xxxxxxxxx>]

Hi Brad,

  Sorry to not have been more verbose. Here is a more complete
example. Only the first column is allowed to be empty. All other are
non-emtpy. There can be any aribtrary empty col#1 (so looking at only
the very preceeding row will not work).

<?xml version="1.0"?>
<table>
  <row>
    <entry>
      <para>Col1 A</para>
    </entry>
    <entry>
      <para>Col2 A</para>
    </entry>
  </row>
  <row>
    <entry>
      <para/>
    </entry>
    <entry>
      <para>Col2 B</para>
    </entry>
  </row>
  <row>
    <entry>
      <para/>
    </entry>
    <entry>
      <para>Col2 C</para>
    </entry>
  </row>
  <row>
    <entry>
      <para>Col1 D</para>
    </entry>
    <entry>
      <para>Col2 D</para>
    </entry>
  </row>
  ...
</table>


It looks like my problem is getting too complex. So I am thinking that
my initial design is poor. Since I have control over the output
format, I am thinking that I could also generate:

<table>
   <col1 name="Col1 A">
     <col2 name="Col2 A"/>
     <col2 name="Col2 B"/>
     <col2 name="Col2 C"/>
   </col1>
   <col1 name="Col1 D">
     <col2 name="Col2 D"/>
   </col1>
  ...
 </table>

I am grouping by common col1 all my entries. It should be slightly
smarted to parse afterward.

Thanks again
-Mathieu
