qbytearray find two similar values

fadu

hi i have data like this
"8800010026020000086A54161565415621" + some another data + "8800010026020000083A352303661445"
i want to find the two index start with "8800010026020000"

 QFile file("somthing");
    file.open(QIODevice::ReadOnly);
    QByteArray data = file.readAll();
    file.close();
    QByteArray patch_data1 = QByteArray::fromHex("8800010026020000");
    int64_t index = data.indexOf(patch_data1);
    qInfo() <<data.mid(index,16).toHex();

@fadu
qsizetype QByteArray::indexOf(QByteArrayView bv, qsizetype from = 0) const takes an optional second parameter where you tell it to start the search from.

@fadu
You have the first match. So go ahead and search after that for the second match, is that what you mean?

fadu

@JonB
yes that's what i mean but it's return the first value only

@JonB
that's it thanks a lot
the problem is solved and this is the new code

  QFile file("test.qcn");
    file.open(QIODevice::ReadOnly);
    QByteArray data = file.readAll();
    file.close();
    QByteArray patch_data1 = QByteArray::fromHex("8800010026020000");
    int64_t index = data.indexOf(patch_data1);
    int64_t index2 = data.indexOf(patch_data1,index+patch_data1.size());
    qInfo() <<data.mid(index,17).toHex()<<index<< data.mid(index2,17).toHex() << index2;
