-:mod:`htmllib` --- A parser for HTML documents
-==============================================
-
-.. module:: htmllib
-   :synopsis: A parser for HTML documents.
-
-
-.. index::
-   single: HTML
-   single: hypertext
-
-.. index::
-   module: sgmllib
-   module: formatter
-   single: SGMLParser (in module sgmllib)
-
-This module defines a class which can serve as a base for parsing text files
-formatted in the HyperText Mark-up Language (HTML).  The class is not directly
-concerned with I/O --- it must be provided with input in string form via a
-method, and makes calls to methods of a "formatter" object in order to produce
-output.  The :class:`HTMLParser` class is designed to be used as a base class
-for other classes in order to add functionality, and allows most of its methods
-to be extended or overridden.  In turn, this class is derived from and extends
-the :class:`SGMLParser` class defined in module :mod:`sgmllib`.  The
-:class:`HTMLParser` implementation supports the HTML 2.0 language as described
-in :rfc:`1866`.  Two implementations of formatter objects are provided in the
-:mod:`formatter` module; refer to the documentation for that module for
-information on the formatter interface.
-
-The following is a summary of the interface defined by
-:class:`sgmllib.SGMLParser`:
-
-* The interface to feed data to an instance is through the :meth:`feed` method,
-  which takes a string argument.  This can be called with as little or as much
-  text at a time as desired; ``p.feed(a); p.feed(b)`` has the same effect as
-  ``p.feed(a+b)``.  When the data contains complete HTML markup constructs, these
-  are processed immediately; incomplete constructs are saved in a buffer.  To
-  force processing of all unprocessed data, call the :meth:`close` method.
-
-  For example, to parse the entire contents of a file, use::
-
-     parser.feed(open('myfile.html').read())
-     parser.close()
-
-* The interface to define semantics for HTML tags is very simple: derive a class
-  and define methods called :meth:`start_tag`, :meth:`end_tag`, or :meth:`do_tag`.
-  The parser will call these at appropriate moments: :meth:`start_tag` or
-  :meth:`do_tag` is called when an opening tag of the form ``<tag ...>`` is
-  encountered; :meth:`end_tag` is called when a closing tag of the form ``<tag>``
-  is encountered.  If an opening tag requires a corresponding closing tag, like
-  ``<H1>`` ... ``</H1>``, the class should define the :meth:`start_tag` method; if
-  a tag requires no closing tag, like ``<P>``, the class should define the
-  :meth:`do_tag` method.
-
-The module defines a parser class and an exception:
-
-
-.. class:: HTMLParser(formatter)
-
-   This is the basic HTML parser class.  It supports all entity names required by
-   the XHTML 1.0 Recommendation (http://www.w3.org/TR/xhtml1).   It also defines
-   handlers for all HTML 2.0 and many HTML 3.0 and 3.2 elements.

-HTMLParser Objects
-------------------
-
-In addition to tag methods, the :class:`HTMLParser` class provides some
-additional methods and instance variables for use within tag methods.
-
-
-.. attribute:: HTMLParser.formatter
-
-   This is the formatter instance associated with the parser.
-
-
-.. attribute:: HTMLParser.nofill
-
-   Boolean flag which should be true when whitespace should not be collapsed, or
-   false when it should be.  In general, this should only be true when character
-   data is to be treated as "preformatted" text, as within a ``<PRE>`` element.
-   The default value is false.  This affects the operation of :meth:`handle_data`
-   and :meth:`save_end`.
-
-
-.. method:: HTMLParser.anchor_bgn(href, name, type)
-
-   This method is called at the start of an anchor region.  The arguments
-   correspond to the attributes of the ``<A>`` tag with the same names.  The
-   default implementation maintains a list of hyperlinks (defined by the ``HREF``
-   attribute for ``<A>`` tags) within the document.  The list of hyperlinks is
-   available as the data attribute :attr:`anchorlist`.
-
-
-.. method:: HTMLParser.anchor_end()
-
-   This method is called at the end of an anchor region.  The default
-   implementation adds a textual footnote marker using an index into the list of
-   hyperlinks created by :meth:`anchor_bgn`.
-
-
-.. method:: HTMLParser.handle_image(source, alt[, ismap[, align[, width[, height]]]])
-
-   This method is called to handle images.  The default implementation simply
-   passes the *alt* value to the :meth:`handle_data` method.
-
-
-.. method:: HTMLParser.save_bgn()
-
-   Begins saving character data in a buffer instead of sending it to the formatter
-   object.  Retrieve the stored data via :meth:`save_end`. Use of the
-   :meth:`save_bgn` / :meth:`save_end` pair may not be nested.
-
-
-.. method:: HTMLParser.save_end()
-
-   Ends buffering character data and returns all data saved since the preceding
-   call to :meth:`save_bgn`.  If the :attr:`nofill` flag is false, whitespace is
-   collapsed to single spaces.  A call to this method without a preceding call to
-   :meth:`save_bgn` will raise a :exc:`TypeError` exception.

-:mod:`sgmllib` --- Simple SGML parser
-=====================================
-
-.. module:: sgmllib
-   :synopsis: Only as much of an SGML parser as needed to parse HTML.
-
-
-.. index:: single: SGML
-
-This module defines a class :class:`SGMLParser` which serves as the basis for
-parsing text files formatted in SGML (Standard Generalized Mark-up Language).
-In fact, it does not provide a full SGML parser --- it only parses SGML insofar
-as it is used by HTML, and the module only exists as a base for the
-:mod:`htmllib` module.  Another HTML parser which supports XHTML and offers a
-somewhat different interface is available in the :mod:`HTMLParser` module.
-
-
-.. class:: SGMLParser()
-
-   The :class:`SGMLParser` class is instantiated without arguments. The parser is
-   hardcoded to recognize the following constructs:
-
-   * Opening and closing tags of the form ``<tag attr="value" ...>`` and
-     ``</tag>``, respectively.
-
-   * Numeric character references of the form ``&#name;``.
-
-   * Entity references of the form ``&name;``.
-
-   * SGML comments of the form ``<!--text-->``.  Note that spaces, tabs, and
-     newlines are allowed between the trailing ``>`` and the immediately preceding
-     ``--``.
-
-A single exception is defined as well:
-
-
-.. exception:: SGMLParseError
-
-   Exception raised by the :class:`SGMLParser` class when it encounters an error
-   while parsing.
-
-:class:`SGMLParser` instances have the following methods:
-
-
-.. method:: SGMLParser.reset()
-
-   Reset the instance.  Loses all unprocessed data.  This is called implicitly at
-   instantiation time.
-
-
-.. method:: SGMLParser.setnomoretags()
-
-   Stop processing tags.  Treat all following input as literal input (CDATA).
-   (This is only provided so the HTML tag ``<PLAINTEXT>`` can be implemented.)
-
-
-.. method:: SGMLParser.setliteral()
-
-   Enter literal mode (CDATA mode).
-
-
-.. method:: SGMLParser.feed(data)
-
-   Feed some text to the parser.  It is processed insofar as it consists of
-   complete elements; incomplete data is buffered until more data is fed or
-   :meth:`close` is called.
-
-
-.. method:: SGMLParser.close()
-
-   Force processing of all buffered data as if it were followed by an end-of-file
-   mark.  This method may be redefined by a derived class to define additional
-   processing at the end of the input, but the redefined version should always call
-   :meth:`close`.
-
-
-.. method:: SGMLParser.get_starttag_text()
-
-   Return the text of the most recently opened start tag.  This should not normally
-   be needed for structured processing, but may be useful in dealing with HTML "as
-   deployed" or for re-generating input with minimal changes (whitespace between
-   attributes can be preserved, etc.).
-
-
-.. method:: SGMLParser.handle_starttag(tag, method, attributes)
-
-   This method is called to handle start tags for which either a :meth:`start_tag`
-   or :meth:`do_tag` method has been defined.  The *tag* argument is the name of
-   the tag converted to lower case, and the *method* argument is the bound method
-   which should be used to support semantic interpretation of the start tag. The
-   *attributes* argument is a list of ``(name, value)`` pairs containing the
-   attributes found inside the tag's ``<>`` brackets.
-
-   The *name* has been translated to lower case. Double quotes and backslashes in
-   the *value* have been interpreted, as well as known character references and
-   known entity references terminated by a semicolon (normally, entity references
-   can be terminated by any non-alphanumerical character, but this would break the
-   very common case of ``<A HREF="url?spam=1&eggs=2">`` when ``eggs`` is a valid
-   entity name).
-
-   For instance, for the tag ``<A HREF="http://www.cwi.nl/">``, this method would
-   be called as ``unknown_starttag('a', [('href', 'http://www.cwi.nl/')])``.  The
-   base implementation simply calls *method* with *attributes* as the only
-   argument.
-
-
-.. method:: SGMLParser.handle_endtag(tag, method)
-
-   This method is called to handle endtags for which an :meth:`end_tag` method has
-   been defined.  The *tag* argument is the name of the tag converted to lower
-   case, and the *method* argument is the bound method which should be used to
-   support semantic interpretation of the end tag.  If no :meth:`end_tag` method is
-   defined for the closing element, this handler is not called.  The base
-   implementation simply calls *method*.
-
-
-.. method:: SGMLParser.handle_data(data)
-
-   This method is called to process arbitrary data.  It is intended to be
-   overridden by a derived class; the base class implementation does nothing.
-
-
-.. method:: SGMLParser.handle_charref(ref)
-
-   This method is called to process a character reference of the form ``&#ref;``.
-   The base implementation uses :meth:`convert_charref` to convert the reference to
-   a string.  If that method returns a string, it is passed to :meth:`handle_data`,
-   otherwise ``unknown_charref(ref)`` is called to handle the error.
-
-
-.. method:: SGMLParser.convert_charref(ref)
-
-   Convert a character reference to a string, or ``None``.  *ref* is the reference
-   passed in as a string.  In the base implementation, *ref* must be a decimal
-   number in the range 0-255.  It converts the code point found using the
-   :meth:`convert_codepoint` method. If *ref* is invalid or out of range, this
-   method returns ``None``.  This method is called by the default
-   :meth:`handle_charref` implementation and by the attribute value parser.
-
-
-.. method:: SGMLParser.convert_codepoint(codepoint)
-
-   Convert a codepoint to a :class:`str` value.  Encodings can be handled here if
-   appropriate, though the rest of :mod:`sgmllib` is oblivious on this matter.
-
-
-.. method:: SGMLParser.handle_entityref(ref)
-
-   This method is called to process a general entity reference of the form
-   ``&ref;`` where *ref* is an general entity reference.  It converts *ref* by
-   passing it to :meth:`convert_entityref`.  If a translation is returned, it calls
-   the method :meth:`handle_data` with the translation; otherwise, it calls the
-   method ``unknown_entityref(ref)``. The default :attr:`entitydefs` defines
-   translations for ``&amp;``, ``&apos``, ``&gt;``, ``&lt;``, and ``&quot;``.
-
-
-.. method:: SGMLParser.convert_entityref(ref)
-
-   Convert a named entity reference to a :class:`str` value, or ``None``.  The
-   resulting value will not be parsed.  *ref* will be only the name of the entity.
-   The default implementation looks for *ref* in the instance (or class) variable
-   :attr:`entitydefs` which should be a mapping from entity names to corresponding
-   translations.  If no translation is available for *ref*, this method returns
-   ``None``.  This method is called by the default :meth:`handle_entityref`
-   implementation and by the attribute value parser.
-
-
-.. method:: SGMLParser.handle_comment(comment)
-
-   This method is called when a comment is encountered.  The *comment* argument is
-   a string containing the text between the ``<!--`` and ``-->`` delimiters, but
-   not the delimiters themselves.  For example, the comment ``<!--text-->`` will
-   cause this method to be called with the argument ``'text'``.  The default method
-   does nothing.
-
-
-.. method:: SGMLParser.handle_decl(data)
-
-   Method called when an SGML declaration is read by the parser.  In practice, the
-   ``DOCTYPE`` declaration is the only thing observed in HTML, but the parser does
-   not discriminate among different (or broken) declarations.  Internal subsets in
-   a ``DOCTYPE`` declaration are not supported.  The *data* parameter will be the
-   entire contents of the declaration inside the ``<!``...\ ``>`` markup.  The
-   default implementation does nothing.
-
-
-.. method:: SGMLParser.report_unbalanced(tag)
-
-   This method is called when an end tag is found which does not correspond to any
-   open element.
-
-
-.. method:: SGMLParser.unknown_starttag(tag, attributes)
-
-   This method is called to process an unknown start tag.  It is intended to be
-   overridden by a derived class; the base class implementation does nothing.
-
-
-.. method:: SGMLParser.unknown_endtag(tag)
-
-   This method is called to process an unknown end tag.  It is intended to be
-   overridden by a derived class; the base class implementation does nothing.
-
-
-.. method:: SGMLParser.unknown_charref(ref)
-
-   This method is called to process unresolvable numeric character references.
-   Refer to :meth:`handle_charref` to determine what is handled by default.  It is
-   intended to be overridden by a derived class; the base class implementation does
-   nothing.
-
-
-.. method:: SGMLParser.unknown_entityref(ref)
-
-   This method is called to process an unknown entity reference.  It is intended to
-   be overridden by a derived class; the base class implementation does nothing.
-
-Apart from overriding or extending the methods listed above, derived classes may
-also define methods of the following form to define processing of specific tags.
-Tag names in the input stream are case independent; the *tag* occurring in
-method names must be in lower case:
-
-
-.. method:: SGMLParser.start_tag(attributes)
-   :noindex:
-
-   This method is called to process an opening tag *tag*.  It has preference over
-   :meth:`do_tag`.  The *attributes* argument has the same meaning as described for
-   :meth:`handle_starttag` above.
-
-
-.. method:: SGMLParser.do_tag(attributes)
-   :noindex:
-
-   This method is called to process an opening tag *tag*  for which no
-   :meth:`start_tag` method is defined.   The *attributes* argument has the same
-   meaning as described for :meth:`handle_starttag` above.
-
-
-.. method:: SGMLParser.end_tag()
-   :noindex:
-
-   This method is called to process a closing tag *tag*.
-
-Note that the parser maintains a stack of open elements for which no end tag has
-been found yet.  Only tags processed by :meth:`start_tag` are pushed on this
-stack.  Definition of an :meth:`end_tag` method is optional for these tags.  For
-tags processed by :meth:`do_tag` or by :meth:`unknown_tag`, no :meth:`end_tag`
-method must be defined; if defined, it will not be used.  If both
-:meth:`start_tag` and :meth:`do_tag` methods exist for a tag, the
-:meth:`start_tag` method takes precedence.
