One more thing.  You might be closing the stream before the xml_archive is destroyed.  This is a common mistake.

  Thanks,

   

  I could get past the header with the "no_header" flag. Also I tried the demo and it puts the </boost_serialization> tag correctly but I do not get that tag in my case.

   

  Does the friend declaration for the stream << operators required in the classes that implement serialization. I do not have this declaration but it seems to work fine.

   

  The other thing is that I get the xml from outside source and when reading in it might have a header which will be different from the one boost has.

   

  That was the reason I wanted to overwrite the init function to have custom header. Now I generate o/p with no header but then still have to read in the header. The only other way is I eat the header. Is there some cleaner?

   

  But at least I know a way around. Thanks fro your time and help.

   

  Thanks,

  Sangeeta

  A couple of things:

   

  a) you might try opening the the archive with the "no_header" flag.

  b) I checked the output of my tests and I see that they do contain the end tag

  </boost_serialization>.  You might try running one of tests and/or demos

  to verify that these work on your system.  If they do, investigate what your

  program is doing differently

  c) I looked in the code in "basic_xml_oarchive.ipp" and it does contain code

  to append </boost_serialization> at the end of the output.  You should

  investigate why this code isn't being called.  If this is due to an error

  in the library- we would be interested in the details.

    Hi,

     

    I have a need to be able to specify my own init routine for the xml serialization. I tried deriving a new archive from xml_oarchive_impl and tried to have a init() function there but that does not get invoked.

     

    I am using boost serialization library ver 1.32.

     

    The xml that is generated by the library is malformed. It generates the following line without corresponding end tag

     

    <boost_serialization signature="serialization::archive" version="3">

     

     

    There is no </boost_serialization> in the o/p xml.

     

    Also my requiremet is that I do not generate this tag.

     

    Thanks,

    Sangeeta
