Hi,

what is the purpose of the comparison?

A) If you just want to test for equality or simple line diffs,
your best bet is probably to serialize the JDOM Document and
use a common diff tool. (However, this can be problematic if the
disk based XML files hasn't been serialized with the same mechanism.
In this case you must employ XML canonicalization on all documents
before doing a comparison).

B) If you want to perform a more sophisticated comparison, e.g.
subtree differences,  there are plenty of XML diff tools available.
Google for "java xml diff".
