Re: Element creation

[Kjell Ahlstedt <kjell ahlstedt bredband net>]

Elements and other nodes are supposed to belong to a document. I don't 
know if you can create "free-floating" elements, but even if it's 
possible, it's probably not a good idea.

My recommendation is that you let getAllNodes() build a document that 
contains the elements you want. It shall return xmlpp::Document*. Then 
use xmlpp::Node::import_node() to copy the elements to where you want them.

The example program 
http://git.gnome.org/browse/libxml++/tree/examples/import_node shows how 
to use import_node(),
and http://git.gnome.org/browse/libxml++/tree/examples/dom_build shows 
how to build a document from scratch. The document it builds contains a 
lot of stuff that you won't need in your document.
