XOM API for Processing XML with Java

[Wolfgang Hoschek <wolfgang.hoschek AT mac.com>]

I'm not sure how you might have got the impression that Nux is, or  
connects to, a database system.
Sorry, but that's not what it's designed for. Rather it's designed to  
operate on streams or main memory trees.

You could override the Saxon collection() function via  
Configuration.setCollectionURIResolver, but this is 1) not really a  
task for beginners as it involves Saxon specific knowledge and 2)  
unlikely to scale in a database setting unless perhaps in very  
specific simple cases.

So, for this sort of functionality, you're probably much better off  
with something like DataDirect XQuery or Oracle's built in beta  
support for XQuery, or similar.
