Delete versions when increasing xml serialization

I just can't find a way to remove version tracking from xmlarchives accelerators.

Example

<Settings class_id="0" tracking_level="0" version="1">
 <px class_id="1" tracking_level="1" version="0" object_id="_0">
  <TestInt>3</TestInt>
  <Resolution class_id="2" tracking_level="0" version="0">
   <x>800</x>
   <y>600</y>
  </Resolution>
  <SomeStuff>0</SomeStuff>
 </px>
</Settings>

I want to enjoy class_id = "0" tracking_level = "0" version = "1" because in this case I just don’t need it and I want a simple clean config as a file

the code

void serialize(Archive & ar, const unsigned int version)
{
  ar & make_nvp("TestInt", TestInt);

  ar & make_nvp("Resolution", resolution);
  ar & make_nvp("SomeStuff", SomeStuff);
}

I found boost :: serialization :: track_never, but nowhere to use it

try creating iarchive with the "no_header" option:

boost::archive::xml_iarchive ia(is, boost::archive::no_header);

it’s too late for the original poster, I would like to share what I found

BOOST_CLASS_IMPLEMENTATION(My_class, object_serializable)

does the trick.

xml,

boost::archive::xml_iarchive ia(is, boost::archive::no_header);

class_id, tracking_level ,

BOOST_CLASS_IMPLEMENTATION( <type>, boost::serialization::object_serializable )
BOOST_CLASS_TRACKING( <type>, boost::serialization::track_never )

. .

BOOST_CLASS_VERSION

( AFAIK), boost::archive::no_tracking, , , ( , XML):

    boost::archive::xml_oarchive oa{std::cout, boost::archive::no_header | boost::archive::no_tracking};
