[Boost-users] [Serialization] xml serialization to file and boost::archive::xml_archive_exception (unrecognized XML syntax)

Hi all

I have a annoying problem with xml serialization to a file or std::cout.
I want to serialize my own classes to a file via filestream and
everytime I get a xml_archive_exception with the error message
unrecognized XML syntax.

What I want to serialize is a child class from a class hierachy. When I
only serialize the part of the mother class (with
BOOST_SERIALIZATION_BASE_OBJECT_NVP) it works, but when I also want to
save the members of the child classes I get this exception.

I have exported every class with BOOST_CLASS_EXPORT and at the base
class I have a BOOST_IS_ABSTRACT(baseClass).

Gcc brings no warnings or errors and when I use a text archive, all
works fine.

Has someone an idea what I do wrong or some suggestions?

Thanks
        Andreas
