Thanks for your interest in libxml++

There is no such feature for now.
To do so there is two ways :

1. Add a function to DomParser to detach a Document from the parser and avoid 
it to be released by the DomParser
for example :
	Document DomParser::detach_document()
or
	Document DomParser::release_document()

2. Give the possibility to detach any node (and all its children) from a tree, 
and to attach it anywhere we want. These could be done with functions like 
Node::attach_node(Node *) / Node::detach_node(Node *).

The 1. should be quite trivial to implement, a patch would be very welcome.
2. implies more reflexion. If someone has ideas on how to do that and want to 
propose a patch, we can discuss it.

Cheers,
