List of all versioned files in subversion? (Remove files by name)

Some smart dude at the office managed to commit a whole bunch of 'backup' files (they start with ._) to our subversion server.

Preferably I would like to delete these files using some basic bash script instead of going through the repository manually.

Is there any way I can get a list of all subversion versioned files inside a directory so I can do some basic grepping / svn deletes?

edit:

'svn list' isn't recursive and also seems to list directories, I need the kind of behavior like 'find'.

second edit:

Ok, the -R flag can make 'svn list' recursive... but how do I strip out directories?
