Insert node Object in other node Object

[gustavomanolo]

I have a root element named "concepts" and i need to add a "concept" but i can't add it with ".ele() function"

let nodeConcepts = xmlBuilder.begin().ele("concepts");
let nodeConcept = xmlBuilder.begin().ele("concept", {
      Quantity: 1,
      Price: 10
    });

nodeConcepts.ele(nodeConcept);

But i get the following error:
RangeError: Maximum call stack size exceeded

I'm trying to do like this, because the node "nodeConcept" can have multiple childs depending on some conditions, and then i add it to the global nodeConcepts to have a final XML tree.

Do you know how to do it? Thanks a lot.
