Tree Tactics

I've got a tree, with arbitrary depth, like..

{
  text => 'This is the top',
  sort => [5,3,7],
  children =>
    3 => {
          text => 'This should be second',
          sort => [4,6],
          children {
             4 => { text=>'a leaf',},
             4 => { text=>'another leaf',},
          },
    5 => ...
    7 => ...
  }
}

I hope you get the idea.

How do I get this to work in Petal?

I figure I should be able to do it with a single template.

myself.xml
==========

<table>
  <tr>
    <td petal:content="object/text">
     This is dummy text 
    </td>
    <td petal:repeat="SOMETHING HERE">
     <xi:include href="./myself.xml" />
    </td>
  </tr>
</table>

What should that repeat be? I can do it with "each:" but then I don't
get any order. I want the order to be that as described in the sort
array ref.

How does anyone handle recursive trees?

Thanks in advance,
