Read all files in directory

**issima90** · 19th March 2014, 19:03

Hi,
I'm learning to use Qt.
I have to read all XML file existing in a directory.
The code I wrote works well with a single file, but I would have results about all the directory.

Could you suggest me the code that I'd have to paste in my .cpp file that allow me to open a QDialog with the choice of the directory and to select a file per time to read?
Now that piece of code is:

Qt Code:

Switch view

bool DomParser::readFile()
{
   QString fileName =
            QFileDialog::getOpenFileName(this, tr("Open Gate File"),
                                         QDir::currentPath(),
                                         tr("XML Files (*.xml)"));*/
    qDebug() << fileName;
    if (fileName.isEmpty())
        return false;
 
    QFile file(fileName);
    if (!file.open(QFile::ReadOnly | QFile::Text)) {
        QMessageBox::warning(this, tr("SAX Bookmarks"),
                             tr("Cannot read file %1:\n%2.")
                             .arg(fileName)
                             .arg(file.errorString()));
        return false;
    }
    qDebug() << "file opened"; ....

bool DomParser::readFile()
{
   QString fileName =
            QFileDialog::getOpenFileName(this, tr("Open Gate File"),
                                         QDir::currentPath(),
                                         tr("XML Files (*.xml)"));*/
    qDebug() << fileName;
    if (fileName.isEmpty())
        return false;

    QFile file(fileName);
    if (!file.open(QFile::ReadOnly | QFile::Text)) {
        QMessageBox::warning(this, tr("SAX Bookmarks"),
                             tr("Cannot read file %1:\n%2.")
                             .arg(fileName)
                             .arg(file.errorString()));
        return false;
    }
    qDebug() << "file opened"; ....

To copy to clipboard, switch view to plain text mode

This, as I explained, allow me to choose the file and read it. Relevant information will be write into another file so I need all info from all files.
Thank to all.
Please help me!
