MarkLogic - JSON to XML conversion - handling multiple attributes

I have a document as below. 

let j = {
  "PolicyInfo" :
  {
    "id" : "12345",
    "PolNum" : "TestPolicy",
    "NameInfo":
    {
      "idref":"9999",
      "Name":"TestName"
    }
  }
}

My requirement is to convert id (under PolicyInfo) and also idref (under NameInfo) to attributes while converting to XML. I am able to use below code to handle one attribute.

const JsonConfig = json.config('custom');
JsonConfig['whitespace'] = 'ignore';
JsonConfig['attribute-names'] = 'id';
json.transformFromJson(j, JsonConfig)

I tried below options but both of them not working.

JsonConfig['attribute-names'] = ['id','idref'];
JsonConfig['attribute-names'] = ('id','idref');

Is there a way to handle multiple attributes while converting to XML?

Thanks in advance!

Solution

  • Yes, use the Sequence.from function:

    JsonConfig['attribute-names'] = Sequence.from(['id', 'idref']);
