std::string split

Hi,

I am dealing with the http header. it is basically made up of pairs like
the following:

key: value\n\r

Now, I need to capture those values and push them into an associative array,
so basically I am going to use std::string this way:

#include <string>
#include <map>
using namespace std;

map<string, string> header;

Yet, since I am quite new to std::string I'd like to know how to split one
line based on ": ", then I am goit to remove any extra whitespaces by using
my own chomp()

thanks

Do you have access to the std::string functions? There are plenty of them you can use, such as string::find_first_of() and string::substr() to get the values.

The thing is I don't know how to move the splitted elements into an associative hash, for example:

Code:

---

string line = "key: value\r\n";
chomp(line);

map<string,string> hash;

hash.insert(make_pair((...),(...)));

thanks

Ok, I sorted it out...just needed to return pair<string,string> !!

Code:

---

#include <iostream>
#include <string>
#include <map>
#include <stdlib.h>
#include <assert.h>
using namespace std;

void chomp(string&);
pair<string,string> mysplit(string,string);

int main()
{
        map<string,string> hash;

        string line = "key: value\r\n";
        chomp(line);

        hash.insert(mysplit(line, ": "));

        for(map<string,string>::const_iterator it=hash.begin(); it!=hash.end(); ++it)
        {
                cout << it->first << "->" << it->second << endl;
        }

        system("pause");
        return EXIT_SUCCESS;
}

void chomp(string& szString)
{
        string whitespaces(" \t\f\v\n\r");
        size_t found;

        found=szString.find_last_not_of(whitespaces);
        if (found!=string::npos)
                szString.erase(found+1);
        else
                szString.clear();
}

pair<string,string> mysplit(string str, string delim)
{
        string::size_type match = str.find(delim);
        assert(match != string::npos);

        return pair<string,string>(
                string(str.begin(), str.begin() + match),
                string(str.begin() + match + delim.length(), str.end())
                );
}
