19.10. "xml.dom.pulldom" — Support for building partial DOM trees
*****************************************************************

2.0 新版功能.

**Source code:** Lib/xml/dom/pulldom.py

======================================================================

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

警告: The "xml.dom.pulldom" module is not secure against maliciously
  constructed data.  If you need to parse untrusted or unauthenticated
  data see XML vulnerabilities.

   "xml.sax.handler.ContentHandler" implementation that …

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

   …

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

   "xml.sax.handler.ContentHandler" implementation that …
