I have a string like this:

"\r color=\"red\" name=\"Jon\" \t\n depth=\"8.26\" "

And I want to parse this string and create a std::list of this object:

class data
{
    std::string name;
    std::string value;
};

Where for example:

name = color
value = red

What is the fastest way? I can use boost.

EDIT:

This is what i've tried:

vector<string> tokens;
split(tokens, str, is_any_of(" \t\f\v\n\r"));

if(tokens.size() > 1)
{
    list<data> attr;
    for_each(tokens.begin(), tokens.end(), [&attr](const string& token)
        {
            if(token.empty() || !contains(token, "="))
                return;

            vector<string> tokens;
            split(tokens, token, is_any_of("="));
            erase_all(tokens[1], "\"");
            attr.push_back(data(tokens[0], tokens[1]));
        }
    );
}

But it does not work if there are spaces inside " ": like color="red 1".
