             iterparse


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: * attribute_defaults - read default attributes from DTD * dtd_validation - validate (if DTD is available) * load_dtd - use DTD for parsing * no_network - prevent network access * remove_blank_text - discard blank text nodes * remove_comments - discard comments * remove_pis - discard processing instructions
