JXPath (or EL/JEXL) is simply a way of getting a piece of data from a
complex structure (XML or Bean).
Functors can be used for this purpose too (and might perform slightly
faster as the code is real, not interpretted from a parsed string).
However, functors are really intended for deeper problems, specifically
actually performing processing. See

for a good example.
