A SAX parser can notify a text node by calling any number of times the
characters method so you need to accumulate all the information you
receive on the characters method and output the text when you get a
notification different than characters.

There's a subtle common bug here: all _get and _set clo

decorator instead so that you can just write:
class test(object):
@print_name
def a_method(self,this,that):

pass
The definition of print_name is lef

Then you can associate mails to labels by joining all three tables
together on the IDs. Of course you can implement this in memory as well
but you should probably want to store them in so
f 'URL=/media' in line :
icon = instream.filename()
dvc = line[11:-1]
break
Btw, you can delete a file or directory with os.unlink and os.rmdir,
respectively; no need for os.system.

No need for regexp in this case, just use None to specify one or more

It shouldn't come as a surprise if it turns out to be slower, since the
nested function is redefined every time the outer is called. If you
actually call the outer function a lot, you'd better profile it.
