[SOLVED] Opening XML files

JonBriem

Hi!

I'm currently creating a simple game using Qt and I want to have a highscores feature in my game. For that I was going to use an XML file, but I'm having problems with the code. My code looks like this:

QFile highscores(":/statistics/resources/highscores.xml");
    if(highscores.exists())qDebug() << "File exists";
    QDomDocument document;
    QDomElement root = document.createElement("Ranks");
    document.appendChild(root);
    for(int i = 0; i < 10; i++)
    {
        QDomElement entry = document.createElement("Entry");
        entry.setAttribute("Name", "");
        entry.setAttribute("Rank", QString::number(i+1));
        entry.setAttribute("Score",QString::number(0));
        root.appendChild(entry);
    }
    if(!highscores.open(QIODevice::WriteOnly | QIODevice::Text))
    {
        qDebug() << "Failed to open file for writing";
    }
    else
    {
        QTextStream stream(&highscores);
        stream << document.toString();
        highscores.close();
        qDebug() << "Finished";
    }

When I run the program the output is
"File exists"
"Failed to open file for writing"

Can anyone explain why I can't seem to open the file?

cheers,
Jon

@JonBriem said:

    if(!highscores.open(QIODevice::WriteOnly | QIODevice::Text))
    {
    qDebug() << "Failed to open file for writing";
    }

is that path inside the resource file? (which is linked into the exe)

changing the path to
QFile highscores ( "highscores.xml" );
the code below did produce the expected xml file.

QDomDocument document;

void CreateRanks()
{

    QDomElement root = document.createElement ( "Ranks" );
    document.appendChild ( root );

    for ( int i = 0; i < 10; i++ ) {
        QDomElement entry = document.createElement ( "Entry" );
        entry.setAttribute ( "Name", "" );
        entry.setAttribute ( "Rank", QString::number ( i + 1 ) );
        entry.setAttribute ( "Score", QString::number ( 0 ) );
        root.appendChild ( entry );
    }
}

void SaveRanks()
{
    QFile highscores ( "highscores.xml" );
    if ( !highscores.open ( QIODevice::WriteOnly | QIODevice::Text ) ) {
        qDebug() << "Failed to open file for writing";
    } else {
        QTextStream stream ( &highscores );
        stream << document.toString();
        highscores.close();
        qDebug() << "Finished";
    }
}

int main ( int argc, char* argv[] )
{
CreateRanks();
SaveRanks();
}
