{"value":[{"bairro":"A Noite","codigoIBGE":3304144},{"bairro":"Albuquerque","codigoIBGE":3304144},{"bairro":"Aliança","codigoIBGE":3304144}]}

JavaScript action

var bairro = "<bairros>"; 
for( i = 0; i < process.body.value.length; i++ ){ 
  bairro += "<bairro>" + process.body.value[i].bairro + "</bairro>"

How can i transform this XML string to an Object to replace my Response Body ?
On OSB 12c this code doesn't work.

parser = new DOMParser();
xmlDoc = parser.parseFromString(bairro, "text/xml");

Log: ReferenceError: "DOMParser" is not defined. (#6)
