I think the Xerces parser is excellent. Unfortunately the DOM 
implementation is tainted by their use of "deferred node expansion" by 
default. This works reasonably well for larger documents but adds a 
hefty overhead to building the DOM for small documents. It also has the 
unfortunate side effect of making read-only DOM access unsafe for 
multithreaded use (since reading the nodes will actually alter their 
internal representation). I haven't checked if Sun left this enabled for 
the JAXP bundling of Xerces, but assume they did.
