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...
