Yeah, I've been working on a program that generates a report about a
repository, using a verbose XML log file.

 From my experience, the output of "svn log REPOS --xml -v" is reliable
for just about everything, except properties and file sizes. Though it
sounds like you need the file content.

You can use the dump file, but it's not XML! If it's a complete
dumpfile (from rev 0 onwards) then you can get as much data as you want
from it.

I have done some ad-hoc dump file parsing, but the preferred method is
to use libsvn_repos, just as svnadmin does. You set up hooks to process
each path in the file. Though, since you're interested in file changes,
you'll need to do diff'ing or something between revisions.
