easiest Way QString can do

[wysota]

Using QRegExp:

QRegExp rx(":([0-9A-F]{2})([0-9A-F]{4})([0-9A-F]{2})([0-9A-F]*)([0-9A-F]{2})");
QString str = "...";
QStringList fields;
if(rx.exactMatch(str)) fields = rx.capturedTexts();

QRegExp rx(":([0-9A-F]{2})([0-9A-F]{4})([0-9A-F]{2})([0-9A-F]*)([0-9A-F]{2})");
QString str = "...";
QStringList fields;
if(rx.exactMatch(str)) fields = rx.capturedTexts();

What about QByteArray? While reading file you can fill the instance of it ...

QRegExp is good ,i am not too familiar with it (need some work on my part ) . If you guys can lead me the way on how to break

dd is a data field that represents one byte of data.

into pairs using QRegExp I will highly appreciate it

What do you want to break here? If you have to characters in a string that represents a hexadecimal number, use QString::toInt() and you're done.

I am trying to break the data line into bytes

fields.at(3) // data of the hex line

fields.at(3) // data of the hex line

from the code below

QRegExp rx(":([0-9A-F]{2})([0-9A-F]{4})([0-9A-F]{2})([0-9A-F]*)([0-9A-F]{2})");QString str = "...";QStringList fields;if(rx.exactMatch(str)) fields = rx.capturedTexts();

QRegExp rx(":([0-9A-F]{2})([0-9A-F]{4})([0-9A-F]{2})([0-9A-F]*)([0-9A-F]{2})");QString str = "...";QStringList fields;if(rx.exactMatch(str)) fields = rx.capturedTexts();

sorry i mess up my cut and paste in the prior reply

QString str = fields.at(3);
for(int i=0;i<str.size();i+=2)
  qDebug() << str.mid(i,2).toInt(0, 16);

QString str = fields.at(3);
for(int i=0;i<str.size();i+=2)
  qDebug() << str.mid(i,2).toInt(0, 16);
