Sample function for parsing a QXmlStreamReader (or part thereof) to a QVariant tree.
QVariantMap xmlStreamToVariant(QXmlStreamReader &xml, const QString &prefix = QLatin1String("."), const int maxDepth = 1024)
{
if (maxDepth < 0) {
qWarning() << QObject::tr("max depth exceeded");
return QVariantMap();
}
if (xml.hasError()) {
qWarning() << xml.errorString();
return QVariantMap();
