De-flattening an XML tree

Hi,

I'm kind of stuck on ideas for how I might de-flatten a tree. It seems
that I can't get the position of the next sibling with some property and I
end up going around in circles with checking siblings because filter
predicates seem to only work with one node at a time.

If I've got something like;

<recordset>
  <record/>
  <data/>
  <data/>
  <record/>
  <data/>
  <record/>
  <data/>
  <data/>
  <data/>
</recordset>

ie. we've got a record tag, followed by it's "children".

Is there any way of transforming this to:
<recordset>
  <record>
    <data/>
    <data/>
  </record>
  <record>
    <data/>
  </record>
  <record>
    <data/>
    <data/>
    <data/>
  </record>
</recordset>


Any suggestions, ideas or strategies?

Thanks a lot!
