Hi Rob,

Maps in XQuery have been defined to be unordered. Using sequences (or arrays) of maps is one way to preserve order. You could also have a look at Leo’s awesome data structures written in XQuery (look for ordered-map.xqm):

Hi Christian,

In my casus I’m exporting and importing xQuery maps where the export-format is a xQuery-file or a json-file. Hereby the sequence of the exported map-entries is important: I want the sequence in which the entries are generated to stay in tact when exporting. I can’t get this working.

My current work-around is to place the map-entries in an array. It does the trick but it feels redundant.

Is there a way to have this kind of control over map-entry sequence?

Thnx in advance,

Rob Stapper
