Splitting a string of bytes to vector of BYTES in C++

Question

I have a string of bytes that looks like the following:

"1,3,8,b,e,ff,10"

How would I split this string into an std::vector of BYTEs containing the following values:

[ 0x01, 0x03, 0x08, 0x0b, 0x0e, 0xff, 0x10 ]

I'm trying to split the string using ',' as the delimiter, but I'm having some trouble getting this to work. Can someone give me a helping hand on how to accomplish this?

So I have tried this:

    std::istringstream iss("1 3 8 b e ff 10");
    BYTE num = 0;
    while(iss >> num || !iss.eof()) 
    {
        if(iss.fail()) 
        {
            iss.clear();
            std::string dummy;
            iss >> dummy;
            continue;
        }
        dataValues.push_back(num);
    }

But this pushes the ascii byte values into the vector:

49 //1
51 //3
56 //8
98 //b
101 //e
102 //f
102 //f
49 //1
48 //0

I'm instead trying to fill the vector with:

 0x01
 0x03
 0x08
 0x0b
 0x0e
 0xff
 0x10

You've just been missing to adapt some small issues appearing with your use case for the linked answer from my comment:

    std::istringstream iss("1,3,8,b,e,ff,10");
    std::vector<BYTE> dataValues;

    unsigned int num = 0; // read an unsigned int in 1st place
                          // BYTE is just a typedef for unsigned char
    while(iss >> std::hex >> num || !iss.eof()) {
        if(iss.fail()) {
            iss.clear();
            char dummy;
            iss >> dummy; // use char as dummy if no whitespaces 
                          // may occur as delimiters
            continue;
        }
        if(num <= 0xff) {
            dataValues.push_back(static_cast<BYTE>(num));
        }
        else {
            // Error single byte value expected
        }
    }
