How to override the init() in the xml serialization library..
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
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.

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.

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

Hi, The </boost_serialization> end tag gets written when I use a file as the outputstream. When I use a string as the outputstream I do not get this tag even if I flush the stream. Probably some problem with the oStringStream. Flush or adding a endl also does not work.
