Editing a text file

Hi
I want to edit a list of text files but my code doesn't work an it's driving me crazy.
I want to replace all the ' < ' & ' > ' with ' " ' .
Is there something wrong with this code?

for (int i=0; i<copiedFiles.count(); ++i)
{
QString contents;

    QFile ifile(copiedFiles.at(i));
    if (ifile.open(QIODevice::ReadOnly))
    {
        QTextStream istream(&ifile);

        istream >> contents;
    }
    ifile.close();

    for (int j=0; j<contents.count(); ++j)
    {
        if (contents[j] == '<' || contents[j] == '>')
        {
            contents.replace(j,1,QChar('\"'));
        }
    }

    QFile ofile(copiedFiles.at(i));
    if (ofile.open(QIODevice::WriteOnly))
    {
        QTextStream ostream(&ofile);

        ostream << contents;
    }
    ofile.close();
}

my code doesn't work

It would be helpful if you said what "doesn't work" means.

As for the code, istream >> contents; reads only the first word from the file.
If you want the whole thing use contents = istream.readAll(). Also, you don't need to iterate over every letter. There's a replace() overload that replaces every occurance, so instead of the loop you can just do

contents.replace(">", "\"");
contents.replace("<", "\"");
