Hi, Florent:
Much the way JavaScript objects turn into json:object values in XQuery,
JavaScript arrays turn into json:array values in XQuery.
When appropriate, you can use json:array-values() to convert a json:array
value to a sequence.
Hoping that helps,
Erik Hennum

Subject: Re: [MarkLogic Dev General] Accessing properties of in-memory JS
object in XQuery
Hi Geert,
I was mot expecting Europe to still answer at this time, but that was counting
without you ;-) Thank you, it works indeed as a charm.
But it seems I oversimplified my example. The problem actually comes from the
fact that the value is an array of objecst, and just iterating over it like a
sequence of items does not work.
This modified example gives this extra complexity:
xdmp.xqueryEval(
`declare variable $obj external;
$obj ! map:get(., 'name')`,
{ obj: [{ name: 'name', title: 'title' }] });
Regards,

It is a json:object (the map:map specialization)..
Try:
xdmp.xqueryEval(
'declare variable $obj external; map:get($obj, "name")',
{ obj: {name: 'name', title: 'title' }});
Cheers,
Geert
