Проблема XmlListModel при получении из API контактов Google XML

Я пытаюсь отобразить записи из API контактов Google XML data https://developers.google.com/contacts/v3#retrieving_all_contacts со следующим кодом: 

import QtQuick 2.0
import QtQuick.Controls 2.0
import QtQuick.XmlListModel 2.0

Item {
    width: 400
    height: 300

    ListView {
        id: listView
        anchors.fill: parent
        model: model
        delegate: Text {
            id: name
            text: qsTr("title: ") + title
        }
    }

    XmlListModel {
        id: model
        xml: "<feed"
             +" xmlns=\"http://www.w3.org/2005/Atom\""
             +" xmlns:openSearch=\"http://a9.com/-/spec/opensearch/1.1/\""

        +"</entry>"

        +"<!-- Other entries ... -->"

        +"</feed>"

        query: "/feed/entry"
        XmlRole { name: "title"; query: "title/string()" }

        onStatusChanged: {
            if (status == XmlListModel.Null) {
                console.log("Null");
            }
            if (status == XmlListModel.Ready) {
                console.log("Ready");
                console.log(count);
            }
            if (status == XmlListModel.Loading) {
                console.log("Loading");
            }
            if (status == XmlListModel.Error) {
                console.log("Error");
                console.log(errorString());
            }
        }
    }
}

Но, похоже, не работает и нет ошибок в журнале. Я не знаю, если это из-за схемы, так как с простыми примерами все в порядке.

Любая помощь? :)

Вы должны объявить пространство имен, как указано документами :

В вашем случае: 

XmlListModel {
    id: model
    // ...
    query: "/feed/entry"
    XmlRole { name: "title"; query: "title/string()" }
    <b>namespaceDeclarations: "declare default element namespace 'http://www.w3.org/2005/Atom';"</b>
    // ...
...
