Get Perticular String from QString

[Lesiok]

What does it mean not working as per expectation ?

I am getting the output as below

list[0] = 0001f0
list[1] = 9f
list[2] = 80
list[3] = 2a
list[4] = 06
list[5] = bd
list[6] = 40
list[7] = 23
list[8] = 5f
list[9] = 16
list[10] = 8c
list[11] = d8
list[12] = 37
list[13] = 43
list[14] = fb
list[15] = b4
list[16] = a4

but my output should be like below

list[0] = 0001f0
list[1] = 9f 80 2a 06 bd 40 23 5f
list[2] = 16 8c d8 37 43 fb b4 a4

You ask to split with a space so what are you surprised ?
Is this string has a fixed format ? If yes just use QString::left, QString::mid and QString::right methods.

Something like this should work, if your lines are always formatted as you show (a 6-byte hex address first, followed by hex as 8 two-byte groups):

QRegularExpression regExp( "^[0-9a-fA-F]6\\s+|(([0-9a-fA-F]2\\s+)8)+");
string.split( regExp, QString::SkipEmptyParts );

QRegularExpression regExp( "^[0-9a-fA-F]6\\s+|(([0-9a-fA-F]2\\s+)8)+");
string.split( regExp, QString::SkipEmptyParts );

To copy to clipboard, switch view to plain text mode 

Untested, you might have to play around with the regular expression to get it working the way you want. You will probably also have to trim whitespace from the ends of the sub-strings because the regular expression includes the separators as part of the matching.
