Pugixml - Convert xml element content to C++ array

Question

In my xml file I have arrays of ints written as follows: "1 10 -5 150 35", and I am using pugixml to parse it.

I know pugixml provides methods such as as_bool, or as_int, but does it provide an easy way of converting the string representation of an int array to a c++ object, or do I have to parse and separate the string myself? If so, any suggestions on how to do that?

Answer 1

A possibility would be to use std::istringstream. Examples:

#include <iostream>
#include <string>
#include <sstream>
#include <vector>
#include <algorithm>
#include <iterator>

int main()
{
    {
        std::istringstream in(std::string("1 10 -5 150 35"));
        std::vector<int> my_ints;

        std::copy(std::istream_iterator<int>(in),
                  std::istream_iterator<int>(),
                  std::back_inserter(my_ints));
    }

    // Or:
    {
        int i;
        std::istringstream in(std::string("1 10 -5 150 35"));
        std::vector<int> my_ints;
        while (in >> i) my_ints.push_back(i);
    }
    return 0;
}
