Hi Aki,

I think what you want is xmlNode.ns->prefix.

I access namespaces on attributes, and I get to them as 
xmlNode.properties->ns->prefix.

My code checks that both the ns pointer and the ns->prefix pointer are 
non-NULL before comparing the prefix string. I don't remember if that's 
just paranoia or if I discovered cases where NS could be non-NULL while 
ns->prefix was NULL.
