XML and reverse geocoding

Hi i am looking to do reverse geocoding using google api and xml file .

Code:

---

XmlListModel {
            id: cityQuery
            source:"http://maps.google.com/maps/api/geocode/xml?latlng=18.4632,-69.9296&sensor=false"
            query: "/GeocodeResponse/result"
 
            XmlRole {
                name: "formatted_address"
                query: "formatted_address/@data/string()"
            }
        }

---

However , formatted_address returns an empty string. Did i make a mistake ??
