Since signature information must be presented, these are described using the method directive. Since they are attributes which are set by client code, in-text references to these attributes should be marked using the :member: role.\n\nIf you need to parse untrusted or unauthenticated data, see xml-security.\n\nThe !xml.parsers.expat module is a Python interface to the Expat non-validating XML parser. The module provides a single extension type, xmlparser, that represents the current state of an XML parser. After an xmlparser object has been created, various attributes of the object can be set to handler functions. When an XML document is then fed to the parser, the handler functions are called for the character data and markup in the XML document.\n\nThis module uses the pyexpat module to provide access to the Expat parser. Direct use of the pyexpat module is deprecated.\n\nThis module provides one exception and one type object\n\nThe exception raised when Expat reports an error. See section expaterror-objects for more information on interpreting Expat errors.\n\nThe type of the return values from the ParserCreate function.\n\nThe !xml.parsers.expat module contains two functions\n\nReturns an explanatory string for a given error number errno.\n\nCreates and returns a new xmlparser object. encoding [1]_, if specified, must be a string naming the encoding used by the XML data. If it is given it will override the implicit or explicit encoding of the document.\n\nParsers created through !ParserCreate are called \"root\" parsers, in the sense that they do not have any parent parser attached. Non-root parsers are created by parser.ExternalEntityParserCreate . …\n\nAttribution: Adapted from Python Documentation under PSF-2.0.
