Reading delimited blocks in a txt file and puting it in a list of strings

[ChrisW67]

There a many ways to achieve this. Here is one that uses QTextStream to worry about finding the white space delimiter:

#include <QtCore>
#include <QDebug>
 
int main(int argc, char* argv[])
{
    QCoreApplication app(argc, argv);
 
    QFile in("/tmp/data.txt");
    if (in.open(QIODevice::ReadOnly)) {
        QTextStream s(&in);
        while (!s.atEnd()) {
            QString dummy, value;
            s >> dummy; // ignore the first field
            s >> value;
            dummy = s.readLine();   // ignore the remainder of the line
            qDebug() << value;
        }
        in.close();
    }
}

#include <QtCore>
#include <QDebug>

int main(int argc, char* argv[])
{
    QCoreApplication app(argc, argv);

    QFile in("/tmp/data.txt");
    if (in.open(QIODevice::ReadOnly)) {
        QTextStream s(&in);
        while (!s.atEnd()) {
            QString dummy, value;
            s >> dummy; // ignore the first field
            s >> value;
            dummy = s.readLine();   // ignore the remainder of the line
            qDebug() << value;
        }
        in.close();
    }
}

No matter what approach you take you have to read the entire line in order to get to the next line.
