Hi Geert,
Thanks. I am not quite sure how /text() fits in this though :-) Yes,
that's what I am doing now, converting the document to a plain object
in memory, before reverting it back to the document. What I have now
instead of:
xdmp.nodeInsertChild(
fn.doc(uri).next().value.root.foo,
{ three: [ 'tres', 3, 'trois' ] });
is the following:
var doc = fn.doc(uri).next().value.root;
var obj = doc.toObject();
obj.foo.three = [ 'tres', 3, 'trois' ];
xdmp.documentInsert(uri, obj);
But this is rather a hack, as we do have a three node system available.
Regards,
