How do you to export/update a pattern filtered subset of a large repository?

I have a batch processing application that needs to process a subset of documents of a given type in a large SVN repository.
I wish to recursively traverse the repository and only export or update documents that match a pattern.

Ideally I'd prefer to use a recursive pattern in a single export or update command that preserves the parent directory hierarchy for exported/update files.
Ant scripts, for example, support this type of recursive file name pattern using filesets:
   http://ant.apache.org/manual/CoreTypes/fileset.html

I failed to find a straightforward way to do this.
Can you either suggest a solution ... or otherwise I will submit an enhancement request.

Thanks,
Tony O'Hagan
