[xml] root node with namespace

[dhk <dhkuhl optonline net>]

How is a root node created with a namespace?  It seem that to make the 
root node I'd need to have a namespace to use with xmlNewNode() and to 
make a namespace I would need to call xmlNewNs() which requires a node 
as indicated in the following two functions.

xmlNodePtr xmlNewNode(xmlNsPtr ns, const xmlChar *name)

xmlNsPtr xmlNewNs(xmlNodePtr node, const xmlChar *href, const xmlChar 
*prefix)

Which call comes first and how do you create your first node with a 
namespace?

thanks,
Dave
