How do you get the element names for a list of elements in a JSON or XML data source (such as the country codes in Facebook)? Select ALL that apply. Note: One answer is better than the others, and is therefore worth more.

  • kf:names(/records/countries/*)
  • name(/records/countries/*)
  • MAP(COMMULATIVE(REPEAT ( 1, COUNT(/records/countries/*)),”?index”?,DATASOURCE(1ed56f…,CONCAT(“name/records/countries[“,index,”?])”?)
  • /name/records/countries/*/*
