XOM API for Processing XML with Java

["Watson, John" <JWatson AT satelliteinfo.co.uk>]

I couldn't agree more.  My application is an interpreter that generates
XPath expressions and then applies them.  I rely pretty much on the full set
of types that XPath expressions may return.  If XOM restricts itself just to
node-sets, I'm afraid I'm much less inclined to use it.

I think you're assuming a scenario where users like to code in Java and only
use XPath as a last resort. There's another scenario where users hate coding
in Java (all those fiddly iterators) and like to use XPath as much as
possible. There's also a scenario where the Java application with embedded
XPath is machine-generated.

sum(*[@code=23]/@value)
lang('de')
count(../following-sibling::foo) = 0
