Re: [xml] Question about packing...

[Remy HAREL <rharel ext rd francetelecom com>]

Hi,

No, this is what I want because of a bug. I have a strange problem, 
when I dump the tree it crashes if I have written something to the same 
stream just before. I found it recently, but in fact, when I want to 
dump my tree, there is nothing to dump, like if the tree would be empty. 
So I would like to know if I could pack ( something like a "tar" for 
(bad) example ) the xml tree to test it.

cout << "toto" << endl;
xml->dump(cout);

-> crashes

cerr << "toto" << endl;
xml->dump(cout);

-> fine

where dump is :

void SortieXML::dump( ostream &out, const char * encoding )  {
      
   int size = 4096;

   // dump the xml tree to memory with specified encoding
   xmlDocDumpFormatMemoryEnc (docPtr, mem, &size, encoding, 1);


#ifdef __LOG_ON__
   if ( size == 0 ) {
       ostringstream msg;
       msg << "[SortieXML::dump] Erreur lors du vidage de l'arbre dans 
la mémoire "  << endl;
       Log::message(msg, NomDuModule, LOG_ETAPE);
   }
#endif   
  
   // dump the memory to the output stream out
   if ( size > 0 ) {
       out.write((const char*) *mem, size);
   }

   // free the memory
   xmlFree(mem);
  

#ifdef __LOG_ON__
   ostringstream msg;
   msg << "Vidage de l'arbre xml sur un output stream "  << endl;
   Log::message(msg, NomDuModule, LOG_ETAPE);
#endif
}


It works fine in other sub-modules I use, but I have problems in this 
sub-module. It's a pretty huge module, I can't provide the source code.

Thanks,

Remy
