Have you tried running DataDirect XQuery? It's designed to leverage 
document projection and streaming 
(http://www.xquery.com/architecture/), and we do have a variety of 
users (http://www.xquery.com/customers/rlpt.html) successfully 
querying very large documents.

Give it a try; you can download a free 15 days trial from
