New in version 2.0.

``xml.dom.pulldom`` allows building only selected portions of a
Document Object Model representation of a document from SAX events.

   ``xml.sax.handler.ContentHandler`` implementation that ...

class class xml.dom.pulldom.DOMEventStream(stream, parser, bufsize)

   ...

class class xml.dom.pulldom.SAX2DOM([documentFactory])

   ``xml.sax.handler.ContentHandler`` implementation that ...
