Re: [xml-dev] Disk-based XPath Processing

It's not an open source library, but DataDirect XQuery does something 
very similar to what you are looking for, and not just for XPath, but 
for XQuery processing, through a technique called XML Streaming.

See 
http://www.datadirect.com/products/xquery/ddxq_technical_overview/index.ssp 
for a technical overview of the product.
