XML: accessing deep nodes

[wysota]

Why not just use the doc() directive in the query itself?

QXmlQuery query;
query.setQuery("doc(http://www.qtcentre.org/index.php)/html/body/whatever");

QXmlQuery query;
query.setQuery("doc(http://www.qtcentre.org/index.php)/html/body/whatever");

I need to make a post request in order to receive a reply from server

[wysota]

In that case use QXmlQuery::setFocus() and pass it the network reply you receive. Just make sure you do it only after the data you expect has arrived.

Thanks, but still the same problem when I pass a reply as QIODevice. Below is the slot that is connected to QNetworkAccessManager::finished signal, so all the data must be arrived, I think.

void MyClass::authenticationFinished(QNetworkReply *reply)
{
 QXmlQuery query;
 query.setFocus(reply);
 query.setQuery("methodResponse/params/param/value/struct/member[name=\"token\"]/value/string(string)");
 // ...
}

void MyClass::authenticationFinished(QNetworkReply *reply)
{
 QXmlQuery query;
 query.setFocus(reply);
 query.setQuery("methodResponse/params/param/value/struct/member[name=\"token\"]/value/string(string)");
 // ...
}

The following code works fine:

void MyClass::authenticationFinished(QNetworkReply *reply)
{
 QXmlQuery query;
 query.setFocus(reply->readAll()); // !pass the string
 query.setQuery("methodResponse/params/param/value/struct/member[name=\"token\"]/value/string(string)");
 // ...
}

void MyClass::authenticationFinished(QNetworkReply *reply)
{
 QXmlQuery query;
 query.setFocus(reply->readAll()); // !pass the string
 query.setQuery("methodResponse/params/param/value/struct/member[name=\"token\"]/value/string(string)");
 // ...
}
