[Boost-users] [serialization] : NVP macros and template classes

Hello,

I have a template class as a base class I wish to serialize...

In that case, the BOOST_SERIALIZATION_BASE_OBJECT_NVP does not work as 
it introduce < > caracters wich i guess are forbidden in the xml tag...

Is there a nice way to solve this issue ? For now, I am only facing the 
1 parameter case and thus defined a macro :

#define 
BOOST_SERIALIZATION_BASE_OBJECT_TEMPLATE_NVP(classname,templateparameter)   
\
    boost::serialization::make_nvp(                                \
        
BOOST_PP_STRINGIZE(classname)BOOST_PP_STRINGIZE(templateparameter),                                  
\
        boost::serialization::base_object<classname<templateparameter> 
 >(*this)            \
    )

which gives me somme acceptable behaviour...

if I have ClassA<ParameterClass> as a base class

I write BOOST_SERIALIZATION_BASE_OBJECT_TEMPLATE_NVP(ClassA,ParameterClass)
instead of "usual" BOOST_SERIALIZATION_BASE_OBJECT_NVP(BaseClassName)

Regards,

Mathieu
