WG: How to reorder an XML tree?

Hi,

I would like to mostly copy an XML file unmodified. BUT some single sub-tree
should be moved to a different location - regardless of it's original
position.
Example (each of these elements can be quite complex):

<o id="a">
  <o id="b"/>
</o>
<o id="c"/>
<o id="d"/>

should result in

<o id="a"/>
<o id="c"/>
<o id="d">
  <o id="b"/>
</o>

The same XSLT should also process the following input to the output shown
above:

<o id="a"/>
<o id="c">
  <o id="b"/>
</o>
<o id="d"/>

Should be simple - I hope - I'm just a beginner.

Thank you for your help!
