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, 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:

• 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 for related files

• remove_blank_text: discard blank text nodes

• remove_comments: discard comments

• remove_pis: discard processing instructions

• strip_cdata: replace CDATA sections by normal text content (default: True)

• compact: safe memory for short text content (default: True)

• resolve_entities: replace entities by their text value (default: True)

• huge_tree: disable security restrictions and support very deep trees

  and very long text content (only affects libxml2 2.7+)

Other keyword arguments:

• encoding: override the document encoding
• schema: an XMLSchema to validate against
