Qt: Multi Array (from JSON); get to specific child - json

Question

I have the following json
(from Google Distance API)
{
"destination_addresses" : [ "Hannover, Deutschland" ],
"origin_addresses" : [ "Wolfsburg, Deutschland" ],
"rows" : [
{
"elements" : [
{
"distance" : {
"text" : "88,8 km",
"value" : 88790
},
"duration" : {
"text" : "58 Minuten",
"value" : 3473
},
"status" : "OK"
}
]
}
],
"status" : "OK"
}
And like to get the distance values ('text' and 'value')
When I iterate that QJsonArray like that:
QJsonDocument document = QJsonDocument::fromJson(bts);
QJsonObject jsonObject = document.object();
QJsonArray jsonArray = jsonObject["rows"].toArray();
foreach (const QJsonValue & value, jsonArray) {
QJsonObject obj = value.toObject();
foreach (const QJsonValue & v, obj["elements"].toArray()) {
QJsonObject obj2 = v.toObject();
qDebug() << obj2["distance"];
//returns [1]
qDebug() << obj2["distance"].toArray();
//returns [2]
}
}
I should be able to get the values.
However, instead I get this:
[1] =
QJsonValue(object, QJsonObject({"text":"88,8 km","value":88790}) )
[2] =
QJsonArray()
which seems to be empty.
I dont know why that is. Because I do it just like that when getting to the "elements" array from that Json.

About [1]:
obj2["distance"] is an object, not array, with fields "text" and "value", and you should do one more job:
QJsonObject obj2 = v.toObject();
QJsonObject finalObject = obj2["distance"].toObject();
QString text = finalObject["text"].toString();
int value = finalObject["value"].toInt();
or something like this.
[{}, {}, {}] - an array of objects
{"a":{}, "b":{},"c":{}} - object which contains 3 objects.
