    \brief The QDeclarativeDomDocument class represents the root of a QML document

    A QML document is a self-contained snippet of QML, usually contained in a

    single file. Each document has a root object, accessible through

    QDeclarativeDomDocument::rootObject().

    The QDeclarativeDomDocument class allows the programmer to inspect a QML document by

    calling QDeclarativeDomDocument::load().

    The following example loads a QML file from disk, and prints out its root

    object type and the properties assigned in the root object.

    \code

    QFile file(inputFileName);

    file.open(QIODevice::ReadOnly);

    QByteArray xmlData = file.readAll();

    QDeclarativeDomDocument document;

    document.load(qmlengine, xmlData);

    QDeclarativeDomObject rootObject = document.rootObject();

    qDebug() << rootObject.objectType();

    foreach(QDeclarativeDomProperty property, rootObject.properties())

        qDebug() << property.propertyName();
