Subject:Best xQuery engine? Author:Minollo I. Date:03 Feb 2008 11:25 PM
You asked the same question on the DataDirect XQuery discussion forum. Same answer... "best engine" is a very subjective matter; and any honest answer would strongly depend on the use case you have in mind.
As developers of DataDirect XQuery, we can only encourage you to take a look at DataDirect XQuery; you'll find a lot of material describing our XQuery engine, as well as the chance to download and try it for free on http://www.xquery.com
