work with web generated xml

[emental86]

Hello,

I need to work with web generated xml document. If I work with local disk file, everithing's fine:

...
QFile file(url);
if(!file.open(QFile::ReadOnly | QFile::Text)) {
    cout << "chyba!";
    return;
}else{
    cout << "soubor otevren...";
    read(&file);
}
file.close(); 
...

...
QFile file(url);
if(!file.open(QFile::ReadOnly | QFile::Text)) {
    cout << "chyba!";
    return;
}else{
    cout << "soubor otevren...";
    read(&file);
}
file.close(); 
...

To copy to clipboard, switch view to plain text mode 

You see, I send to method read pointer to file (QIODevice). I want to do something like this:

...
QUrl address = QUrl(url);
 
if(!address.open(QFile::ReadOnly | QFile::Text)) {
    cout << "chyba!";
    return;
}else{
    cout << "soubor otevren...";
    read(&address);
}
...

...
QUrl address = QUrl(url);

if(!address.open(QFile::ReadOnly | QFile::Text)) {
    cout << "chyba!";
    return;
}else{
    cout << "soubor otevren...";
    read(&address);
}
...

To copy to clipboard, switch view to plain text mode 

Of course I know, it's wrong. I found only QDesktopServices:penUrl ( const QUrl & url ) but it opens URL in web browser and I don't want this! I need to work with generated xml file.

It crossed my mind that I can save generated document to disk and then can I work with that like I want to. But I think it's soo complicated.

Thx for any answer...

Hello,

can anyone help me, with my problem? I have this code:

#include <iostream>
#include <QApplication>
#include <QIODevice>
#include <QFile>
#include <QTextStream>
#include <QUrl>
#include <QtNetwork>
#include <QHttp>
#include <QObject>
 
int main(int argc, char *argv[]){
        QCoreApplication app(argc, argv);
        QTextStream out(stdout);
        QHttp *http = new QHttp();
        QFile *file = new QFile("index.html");
        file->open(QIODevice::WriteOnly);
        http->setHost("www.trolltech.com");
        out << http->errorString() << endl;
        http->get(QUrl::toPercentEncoding("/index.html"), file);
        out << http->errorString() << endl;
        file->close();
        return 0;
}

#include <iostream>
#include <QApplication>
#include <QIODevice>
#include <QFile>
#include <QTextStream>
#include <QUrl>
#include <QtNetwork>
#include <QHttp>
#include <QObject>

int main(int argc, char *argv[]){
        QCoreApplication app(argc, argv);
        QTextStream out(stdout);
        QHttp *http = new QHttp();
        QFile *file = new QFile("index.html");
        file->open(QIODevice::WriteOnly);
        http->setHost("www.trolltech.com");
        out << http->errorString() << endl;
        http->get(QUrl::toPercentEncoding("/index.html"), file);
        out << http->errorString() << endl;
        file->close();
        return 0;
}

To copy to clipboard, switch view to plain text mode 

And the result is:

Unknown error
Unknown error

I tried many different versions of code, but the result is still that Know anybody what can by wrong?

Thx for all answers...
