Re: [xsl] Yet another grouping question

Now comes the grouping issue.  Cities served by multiple airports are
repeated in the table:

<tr>
  <td>Buenos Aires</td>
  <td>Jorge Newbery</td>
  <td>AEP</td>
</tr>
<tr>
  <td>Buenos Aires</td>
  <td>Ministro Pistarini</td>
  <td>EZE</td>
</tr>

Obviously I'd like both of these airports listed in one city node for Buenos
Aires, but I can't figure out how to modify my stylesheet to do this.  I
don't think I can use methods involving keys

Grouping isn't only accomplished through keys ... I often use variables and variables work across files.

I mocked up some data and the following seems to work fine in a small test.

I hope this helps.
