As to your varying new content, simply handle this with parameters to your XSLT or something like that (perhaps even having different conditional targets that handle different EJB configuration setups in addition to parameterized XSLTs).
Don't panic, take a deep breath and think about just what you're trying to do. Look at the Ant manual's list of core and optional tasks and work out how you can use them address your problem using them.
