Robert,

Here is the relevant code:

===========================================
from the header file for the class being serialized...

#include "boost/serialization/shared_ptr.hpp" 
#include "boost/serialization/nvp.hpp"
#include "boost/date_time/posix_time/ptime.hpp"
#include "boost/date_time/posix_time/time_serialize.hpp"

. . .

private:
        friend class boost::serialization::access;
        template<class Archive>
        void serialize(Archive& ar, const unsigned int version) {
            ar & BOOST_SERIALIZATION_BASE_OBJECT_NVP(WkFlo::RetractionMixin);
            ar & BOOST_SERIALIZATION_NVP(mNode);
            ar & BOOST_SERIALIZATION_NVP(mExportId);
            ar & BOOST_SERIALIZATION_NVP(mExportStart);
        }//serialize()

where mNode is a shared_ptr<>, mExportedId is a string, and mExportStart
is a ptime.
===========================================

from the test source file...

#include "boost/archive/xml_iarchive.hpp"
#include "boost/archive/xml_oarchive.hpp"
#include "boost/serialization/shared_ptr.hpp" 
#include "boost/serialization/nvp.hpp"

. . .

void ExportedNode_Test::serializationTest() {
        const char* archiveFile = "temp/Exported_Node_archive.xml";
        remove(archiveFile); // remove any file with that name
        MockNode_ptr BasicNodeObj1(new MockNode(2312));

        ExportedNode_ptr testObj_out(new ExportedNode(BasicNodeObj1, "abcd"));
       {
                // save data to archive
                ofstream outStream(archiveFile);
                boost::archive::xml_oarchive outArchive(outStream);
                

                // write class instance to archive
                try {
               outArchive << BOOST_SERIALIZATION_NVP(testObj_out);
               } catch (exception& ex) { cerr << "write: " << ex.what() << endl;}
        }	// archive and stream closed when destructors are called

        . . .
}

where the outArchive << is what wrote:

<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
<!DOCTYPE boost_serialization>
<boost_serialization signature="serialization::archive" version="3">
<testObj_out class_id="0" tracking_level="0" version="1">
        <px class_id="1" tracking_level="1" version="0" object_id="_0"</boost_serialization>

and threw the exception: "unrecognized XML syntax"

Is this enough to go on?
