I would like to read a TXT file and extract some data that are in double quotes. I managed to make the code by reading other forums. It works for the first data found. I would like to continue finding for another data on the same line.

//Here is the TXT file content:

sd sdkfjsld lksjdfls pon. 234234; sd;flksd "74.4" lkasjdlsk aslfksjdfls sdlkfjsldf sldkfjsld 342352 ds;flsdkf "256" "sdlkfjds
2873ihwefisjhfs dlkfjlsd fgdf090324i2. 43p530i953kldf,msd ; lsdjkflskfn fdlsmkfsd "8" ..,lmsdlifjodsf sokdjflsdn
0.01
0.02
0.03
0.04

//The code:

void MainWindow::Convert () {

QString filter = "All file (*.txt);; Text file (*.txt)";
QString file_name = QFileDialog::getOpenFileName(this, "Upload file",QDir::homePath(), filter);
QFile file (file_name);

const QRegularExpression regex("\"([A-Za-z0-9_\\./\\-\\s]*)\"");

if(file.open(QFile::ReadOnly | QFile::Text)){
    QTextStream in(&file);

     qDebug() << "Opened file:" << file;

    while(!in.atEnd()){
        const QString lineString = in.readLine(); // read line

        qDebug() << "LineString" << lineString;

        const QRegularExpressionMatch match = regex.match(lineString); // apply the pattern on Text

        if(match.hasMatch()){ // if captured the words
            qDebug() << "Full Capture: " << match.captured(0);
            qDebug() << "Captured Words: " << match.captured(1) << match.captured(2) << match.captured(3) << match.captured(4);
        }
    }
    file.close();
}

}

//Output:
Opened file: QFileInfo(/Users/../Desktop/Tests.txt)
LineString "sd sdkfjsld lksjdfls pon. 234234; sd;flksd "74.4" lkasjdlsk\taslfksjdfls\tsdlkfjsldf\tsldkfjsld 342352 ds;flsdkf "256"\t"sdlkfjds"

Thank you very much
