__init__(self, handler)
(Constructor)

source code 
x.__init__(...) initializes x; see x.__class__.__doc__ for signature
Overrides: object.__init__
(inherited documentation)

parse(self, xml)

source code 

parse the xml using self.handler

xml is supposed to be either a unicode or ascii string, or a string with the character set as defined in the xml declaration

_handle_pis(self, xml)

source code 

handle processing instructions

takes care of handling (if appropriate) the XML declaration, and of discarding any processing instructions and document type declarations etc. the lib can't deal with

returns unicode, if the input string is not already unicode the charset mentioned in the XML declaration will be used for conversion (if any)

_parse_into_chunks(self, xml)

source code 
None

_parse_start(self, lineno, data)

source code 
None

_test(self, assertion, lineno, message)

source code 
raises an exception with message as text when assertion is false
