Question

How to save c++ object into a xml file and restore back?

Answer 1

Serialization is a complex topic which is probably too much for a simple answer on SO. Unfortunately with C++, you don't get it for free as in other languages.

See the C++ faq lite or boost for a start.

Answer 2

Boost's serialization library might be implementing a lot of the functionality you are looking for.

Answer 3

I don't know if any direct way of achieving this. You can write separate methods to serialize and de-seriealize methods in which individual data members of the object need to be written and extracted from the file.

Answer 4

Boost.Serialization and libs11n can both do this. The libs11n manual (available here) has an extensive comparison of the two.

As Tobias said, the C++ FAQ has good background information.
