If you document is reasonably complex I usually define some modes like:
BPML_BOOTSTRAP_MODE = 0
BPML_PACKAGE_MODE = 1
BPML_PROCESS_MODE = 2
BPML_CONTEXT_MODE = 3
....
BPML_EVENT_MODE = 10
BPML_FAULTS_MODE = 11
BPML_ATTRIBUTES_MODE = 12
- so I can self.mode.append(BPML_PROCESS_MODE) when I enter an element
(startElement) and self.mode = self.mode[:-1] when I leave an element
(endElement). This provides you with a complete 'stack trace' of how
you got where you are and still lets you efficiently process the stream
[verses using evil document model]. In startElement you can check the
current mode and tag with something like -
...
elif (name == 'event' and self.mode[-1] -- BPML_PROCESS_MODE):
...
