I've done this two different ways. The simple way is very similar
to what you are now doing. It sucks because I have to manually
maintain the list of subdirectories to traverse every time I
create a new subdir.

Here's the other way, using glob and isdir from os.path, adapted
from actual production code.

class Miner:
    def __init__(self, archive):
        # setup goes here; prepare to acquire the data
        self.descend(os.path.join(archive, '*'))

    def descend(self, path):
        for fname in glob.glob(os.path.join(path, '*')):
            if os.path.isdir(fname):
                self.descend(fname)
            else:
                self.process(fname)

    def process(self, path):
        # Do what I want done with an actual file path.
	# This is where I add to the data.

In your case you might not want to process unless the path also
looks like an xml file.

mine = Miner('myxmldir')

Hmmm... I might be doing too much in __init__. ;)
