If you want to recursively work through subdirectories,
you should have a look at os.path.walk.

os.chdir(...)

glob.glob('*.xxx')

f =3D file(filename, 'rt')
text =3D f.read()

Have a look at the os.path module to get things
portable.

I'm not quite sure what you intend here. What would
you want from "XXX<asd>12123123<asd/>XXX"?
a) <asd>12123123<asd/>
or
b) <asd/>
?

import re
re.findall(r"(<.+?/>)",text)    # case a
re.findall(r"(<[^>]+?/>)",text) # case b

Actually, to make case a handle line breaks in tags you need

pat =3D re.compile(r"(<.+?/>)",re.DOTALL)
pat.findall(text)

I'll let you figure out the rest.
