Because I do some tests before and calling xmlParseBalancedChunkMemory() 
initialized doc->children with the result node llist. But it seems that 
this happens only if doc->children is NULL (Is this a bug ?). At this 
time, I (wrongly) concluded that when a doc argument was provided, 
xmlParseBalancedChunkMemory() replaces doc->children with the result 
nodes of parsing.
OK! now I do the following instead
xmlNodePtr nodeList;
if (xmlParseBalancedChunkMemory(node->doc, NULL, NULL, 0, (xmlChar *)str, &nodeList) == 0)
{ 
    if (xmlAddChildList(node, nodeList) == NULL)
    {
       ...
    }
}
Thank you for your help.
