This makes it rather hard to just get a list of block devices without repeating the same code. So here I've factored out the common code for parsing block devices into a separate function and callback.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 devicesand a callback to receive each one, I'd have the new function just be responsible for parsing a single block device. Keep iteration over blockdevices 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
I'm not sure I understand. Do you mean the function would parse a block device and return a structure?
