Split hex encoded string

azarubkin

How do I split hex encoded string into substrings of 2 characters?
Example: "806982" -> "80", "69", "82".

I tried:

QString s = "806982";
QRegExp re("[\\da-fA-F]{2}"); // exactly 2 hex digits
QStringList l = s.split(re);

but it did not work as intended.

You can use a regular expression in a loop:

QString s = "806982";
QRegExp re("([\\da-fA-F]{2})"); // exactly 2 hex digits
QStringList l;

int pos = 0;

while ((pos = re.indexIn(s, pos)) != -1) {
    l << re.cap(1);
    pos += re.matchedLength();
}
