Hi, I was trying out boost serialization and ran into a snag. If I serialize the same object onto two xml_oarchives, one constructed with a ostringstream and one constructed with an ofstream, I get differing results - the file based xml is well formed, but the string based xml is missing its final closing tag. Here is the generating code snippet: // now serialize ostringstream os; boost::archive::xml_oarchive ar(os); ofstream ofs("/home/sternlbe/boo.xml"); boost::archive::xml_oarchive ar2(ofs); Portfolio& port = *p; ar << BOOST_SERIALIZATION_NVP(port); ar2 << BOOST_SERIALIZATION_NVP(port); string s = os.str(); LOG_DEBUG(logger) << "Xml string: \n" << s; For the file output, I get the (correct) result: <?xml version="1.0" encoding="UTF-8" standalone="yes" ?> <!DOCTYPE boost_serialization> <port class_id="0" tracking_level="1" version="0" object_id="_0"> 2124433 This is a stub! 0 </port> However, the string result is missing the final line (closing tag): <?xml version="1.0" encoding="UTF-8" standalone="yes" ?> <!DOCTYPE boost_serialization> <port class_id="0" tracking_level="1" version="0" object_id="_0"> 2124433 This is a stub! 0 </port> Any thoughts?
