Please help me with the following problem:I try to construct the current status of a series of objects along the following simple rules: * the current status of on object with a certain `identificatie` (id) is the newest version of that object * except when the newest object has the property `<status>beëindigen</status>` then the object stops existing. I use a fold-left to proces these rules with a simple function implementing those rules. This gives me unexpected results. I've reduced the problem to a single stand alone query in which the last object (`obj3`) has the property `<status>beëindigen</status>`. So I would expect this line: `let $stand4 := fold-left(($obj3, $obj2, $obj1), (), function($stand, $obj) { local:stand-totaal($stand, $obj) })` to give me an empty result as `obj3`has the property <status>beëindigen</status> but I am getting `obj1` as demonstrated in the following stand alone query.
At least another XQuery 3.1 processor that BaseX (tried with SaxonC HE 12.4) also outputs 3 <-> 2 <-> 1 ============ <sl:stand xmlns:sl="http://www.geostandaarden.nl/bestanden-ow/standlevering-generiek";> <ow-dc:owObject xmlns:ow-dc="http://www.geostandaarden.nl/imow/bestanden/deelbestand"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";> <r:RegelVoorIedereen xmlns:r="http://www.geostandaarden.nl/imow/regels";> <r:identificatie>nl.imow-mnre1034.juridischeregel.OR0000000027</r:identificatie> <r:idealisatie>http://standaarden.omgevingswet.overheid.nl/idealisatie/id/concept/Exact</r:idealisatie> <r:artikelOfLid> <r:RegeltekstRef xmlns:xlink="http://www.w3.org/1999/xlink"; xlink:href="nl.imow-mnre1034.regeltekst.OR0000000027"/> </r:artikelOfLid> <r:thema>http://standaarden.omgevingswet.overheid.nl/thema/id/concept/WaterEnWatersystemen</r:thema> <r:locatieaanduiding> <l:LocatieRef xmlns:l="http://www.geostandaarden.nl/imow/locatie"; xmlns:xlink="http://www.w3.org/1999/xlink"; xlink:href="nl.imow-mnre1034.ambtsgebied.LND6030B"/> </r:locatieaanduiding> </r:RegelVoorIedereen> </ow-dc:owObject> </sl:stand> so it looks, if that is not the result you want, as if the problem is likely in your code.
