Hi, I am trying to learn how to read an XML file using boost-serialization. The code snippet of a sample program is as follows : void restore_schedule(bus_schedule &s, const char * filename) { // open the archive std::ifstream ifs(filename); assert(ifs.good()); boost::archive::xml_iarchive ia(ifs); // restore the schedule from the archive ia >> BOOST_SERIALIZATION_NVP(s); } First few lines of demo.xml are as follows : <?xml version="1.0" encoding="UTF-8" standalone="yes" ?> <?xml-stylesheet type="text/xsl" href="XSLTFile.xsl"?> <!DOCTYPE boost_serialization> <boost_serialization signature="serialization::archive" version="6"> But this gives me below error : $ ./a.out terminate called after throwing an instance of 'boost::archive::xml_archive_exception' what(): unrecognized XML syntax If I remove the line : <?xml-stylesheet type="text/xsl" href="XSLTFile.xsl"?> from demo.xml then it works fine. Can you please let me know if there is any workaround for this problem? Currently I am using Fedora Core 13 with boost-serialization-1.41.0-7.fc13.i686. Is this case handled in latest boost release?
