These are in the _class_ itself, so they will be shared by all its
instances. You should so something like this instead:
def __init__(self):
self.content = ''
self.markup = []
self.span_stack = []
Yes.. tested that and SGMLParser won't let me override __init__,
(SGMLParser vars are uninitialized even with sgmllib.SGMLParser(self) call).
OK, so SGMLParser needs to be initialised:
def __init__(self):
sgmllib.SGMLParser.__init__(self)
self.content = ''
self.markup = []
self.span_stack = []
Tried some but not the following:
with a differently named init function and one boolean class var 'initialized'
it can check 'if self.initialized' in front of each handler. Does the trick.
Confusion dissolved :)
thanks.
