Exporting MgdSchema objects

Midgard CVS HEAD supports nice and quite usefull export method for MgdSchema objects. It is quite simple to export objects on PHP level.

A code example for exporting whole sitegroup ( SG0 in this case ):

foreach ($_MIDGARD['schema']['types'] as $type => $val){

        $replication_data_dir = "/some/path";
        $qb = new midgard_query_builder($type);
        $qb->add_constraint("guid", "<>", " ");
        $ret = $qb->execute();

        foreach ($ret as $object){

          $filepath = $replication_data_dir."/".$type."_".$object->guid.".xml";
          $dump_file = fopen($filepath, 'w');
          $xml = $object->export();              

          if($xml) {
                 fwrite($dump_file, $xml);
                 fclose($dump_file);
          } else {
                 echo mgd_errstr();
          }
    }
 unset($object);
}

If you try to execute this code twice , you should get MGD_ERR_OBJECT_EXPORTED errno returned for every export method call.
