I agree that its good to separate this code out, however, I'd split it
slightly differently. Instead of a function to parse all block devices
and a callback to receive each one, I'd have the new function just be
responsible for parsing a single block device. Keep iteration over block
devices in the caller & avoid the callback. This is more in keeping with
the style of the other functions for parsing XML & related domain info
formats

Dan.
