The way you're using xargs is essentially a no-op here, since the output 
is no different than if you skipped the xargs part.

However, if you put the action code into a separately executable script 
file that takes multiple arguments and gave that command to xargs, 
you'd have what you want.

So if your script was something like this:

-==--==--==--==--==--==--==--==--==--==--==--==--==--==--==-
#!/bin/bash --norc

    for arg; do

        # Do stuff with "$arg" (always quote it!)

    done
-==--==--==--==--==--==--==--==--==--==--==--==--==--==--==-


Then just invoke it like this:

% for file in $(find * -print0 | xargs --null scriptName)

By the way, these braces are redundant.
