Sorry, I can't explain this. a) I can't explain how output code would through an exception "unrecognized XML syntax" which should only be invoked when an archive is read. b) the "

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>

and threw the exception: "unrecognized XML syntax"

Is this enough to go on?
