You have to split the complete processing over several EPI queries where a<br>
single query returns all elements with level=1 for a particular subfolder.<br>
You can sort_on='position' within each query. And paste the results in some<br>
way together. Nobody said that EPI would solve the problem out-of-the-box<br>

Right, so with sufficient levels you end up with a *lot* of queries.<br>
<br>
Why not just query for the whole lot and use one method that returns a<br>
(path, position) tuple for a given item, and pass that to the sort<br>
function as the key keyword? Should be a lot better performing.<br>

If this would be a programming contest then you would cache the results and don't care about the performance for the initial calculation.<br><font color="#888888">
