How to serialize this class into XML or JSON

I have a list of objects derived from a class named "Campus" which contains two strings, one int and two lists : one for "Students", the other is for "Teachers", before closing the program, I want to save the campus objects and of course the "Student" and "Teachers" objects contained on their lists, I want to serialize those data in an XML or JSON format or even anything else then store the result in a file.

Can somebody give me the fastest way to do the serialization with a library (that is not heavy as boost) in XML or JSON or another solution. When it comes to deal with JSON or XML serialization, I don't know what to do ! EDIT: is this feasible with RapidJSON ?

class Campus
{
private:
    std::string city;
    std::string region;
    int capacity;
    std::list<Student> students;
    std::list<Teacher> teachers;
}

class Student
{
private:
    int ID;
    std::string name;
    std::string surname;
}

class Teacher
{
protected:
    int ID;
    std::string name;
    std::string surname;
};

You can use this C++ serialization library : Pakal persist 

#include "XmlWriter.h"


class Campus
{
private:
    std::string city;
    std::string region;
    int capacity;
    std::list<Student> students;
    std::list<Teacher> teachers;

public:

    void persist(Archive* archive)
    {
        archive->value("city",city);
        archive->value("region",region);
        archive->value("capacity",capacity);

        archive->value("Students","Student",students);
        archive->value("Teachers","Teacher",teachers);
    }

}

class Student
{
private:
    int ID;
    std::string name;
    std::string surname;

public:

    void persist(Archive* archive)
    {
        archive->value("ID",ID);
        archive->value("surname",surname);
        archive->value("name",name);        
    }

}

class Teacher
{
protected:
    int ID;
    std::string name;
    std::string surname;
public:

    void persist(Archive* archive)
    {
        archive->value("ID",ID);
        archive->value("surname",surname);
        archive->value("name",name);
    }
};

Campus c;

XmlWriter writer;
writer.write("campus.xml","Campus",c);

Unfortunately C++ doesn't support reflection, so it can't automagically figure out the parameter names.. but check out this answer which looks like it'll be close to what you want: https://stackoverflow.com/a/19974486/1715829
