[xml] Memory leak / cleanup missing after node creation.

	Hi, I am observing a leak when performing this walk/replace through 
nodes:

static void process_XML_elements(xmlNode *a_node)
{
xmlNode *newNode = NULL;
xmlNode *cur_node = NULL;
        
        for (cur_node = a_node; cur_node; cur_node = cur_node->next) {
                switch(cur_node->type)
                {
                        case XML_ELEMENT_NODE:
                                if(!strcmp("aTest", cur_node->name))
                                {

                                        newNode = xmlNewText(theTagReplacements[1]);
                                        xmlReplaceNode(cur_node, newNode);

                                }
                        break;

                        default:
                        break;

                }

                process_XML_elements(cur_node->children);
        }
}


	'xmlFreeDoc' clears up the doc allocation but not the nodes assigned 
above to replace the previous nodes.  A kludge would be to maintain a 
list of allocated nodes then freeing them individually, but it would be 
nice if 'xmlFreeDoc' or similar freed all the nodes assigned to the doc 
itself.


Regards,
                Jose.
