Look for a solution within Apache but outside the SVN code. I don't
know exactly how to solve this, but it will involve another Apache
component (PHP? Filters? mod_something?) doing a sub-request (or
whatever the Apache terminology is) that is handled by Subversion's
modules in the normal way, and then processing the result of that
sub-request before returing it to the browser.

Look, for example, at how the various Subversion web-based repository
browsers work. They can present HTMLified program source code which has
been colour-coded according to the language's syntax rules; this is done
by getting the raw code from Subversion and then processing it before
returning it to the browser.

You certainly don't want to be doing it using hook scripts.

Good luck!
