Thread: C++ convert JSON to XML

I am looking for a way to convert JSON to XML In C++.
For this we have evaluated PICOJSON and Pugixml.

I need some guidance and approach during initial coding on how to do this.

I am thinking of first Parsing the JSOn into and Object and then Iterated the Object recursively and construct XML using Pugixml

Code:

#include <iostream>
#include "include/picojson.h";
#include "include/pugixml.hpp";
using namespace std;
int main() {
   
    const char* json =
        "{"menu": {"
        ""id": "f","
        ""popup": {"
        "  "menuitem": ["
        "    {"v": "0"},"
        "    {"v": "1"},"
        "    {"v": "2"}"
        "   ]"
        "  }"
        "}"
        "}";
    //const char* json = "{"a":1}";
    picojson::value v;
    std::string err;
    const char* json_end = picojson::parse(v, json, json + strlen(json), &err);
    std::string jsonres = v.serialize();
   
    std::cout << v;
    //How should I iterate on this "v" or "jsonres"


    return 0;
}

How can I iterate the Parsed JSON Object, could someone guide me with initial code/sudo code

I mixed visual studio versions and Now I had to remove everything because it bugged everything... Any ways once I got a working setup I would give you a better answer but here is my take any ways and I hope it helps.


Firstly always write the initial result to debug so you have a clue what is going on with the output.
Secondly, XML is a true Array, whilst Json is just more of an object that is like an array.


I'd say you have two approaches either you use this library to do it for you "http://www.boost.org/doc/libs/1_55_0/doc/html/property_tree.html" or manually add + i iteration you may have used
inside of loop functions before "https://www.example-code.com/cpp/json_array_iterate.asp"
