Class iterparse

        iterparse

iterparse(self, source, events=("end",), tag=None, attribute_defaults=False, dtd_validation=False, load_dtd=False, no_network=True, remove_blank_text=False, remove_comments=False, remove_pis=False, encoding=None, html=False, recover=None, huge_tree=False, schema=None)

Incremental parser.

Parses XML into a tree and generates tuples (event, element) in a SAX-like fashion. event is any of 'start', 'end', 'start-ns', 'end-ns'.

For 'start' and 'end', element is the Element that the parser just found opening or closing. For 'start-ns', it is a tuple (prefix, URI) of a new namespace declaration. For 'end-ns', it is simply None. Note that all start and end events are guaranteed to be properly nested.

The keyword argument events specifies a sequence of event type names that should be generated. By default, only 'end' events will be generated.

The additional tag argument restricts the 'start' and 'end' events to those elements that match the given tag. By default, events are generated for all elements. Note that the 'start-ns' and 'end-ns' events are not impacted by this restriction.

The other keyword arguments in the constructor are mainly based on the libxml2 parser configuration. A DTD will also be loaded if validation or attribute default values are requested.

Available boolean keyword arguments:
