[xml] Only through experimentation :o) XML and memory

[Jose Commins <axora myrealbox com>]

	This is a question specifically to Daniel, but thought it would be 
useful if posted publicly.

	As proabably gathered from my previous posts, I have been 
experimenting with different schemes and node management with libxml2.

        Now, I am doing a lot of this in my code:

                        newNode = xmlNewDocText(cur_node->doc, "blah");
                        xmlReplaceNode(cur_node, newNode);
                        xmlFreeNode(cur_node);
                        cur_node = newNode;


Then right at the end, I have:

                        xmlFreeDoc(doc);


	Being very pendantic (hence lots of trial and error - my code has to 
have *zero* memory leaks) I had an assumption that the 'newNode' above 
created with 'xmlNewDocText' would need to be cleared later, but from 
my leaks tests I see that 'xmlFreeDoc' takes care of any externally 
allocated nodes.  I want to make sure my assumption is right, that 
'xmlFreeDoc' will also deallocate/free any new nodes linked in to the 
doc?

	I have to add that, after many weeks of extensively using libxml2, I 
have found it to be one of the best libraries/API's I have ever used.  
The documentation needs a few tweaks, though!  ;o)


Regards,
                Jose.
