        html5lib is a pure-python library for parsing HTML. It is designed to
        conform to the WHATWG HTML specification, as is implemented by all major
        web browsers.
        
        
        Usage
        -----
        
        Simple usage follows this pattern:
        
        .. code-block:: python
        
          import html5lib
          with open("mydocument.html", "rb") as f:
              document = html5lib.parse(f)
        
        or:
        
        .. code-block:: python
        
          import html5lib
          document = html5lib.parse("<p>Hello World!")
        
        By default, the ``document`` will be an ``xml.etree`` element instance.
        Whenever possible, html5lib chooses the accelerated ``ElementTree``
        implementation (i.e. ``xml.etree.cElementTree`` on Python 2.x).
        
        Two other tree types are supported: ``xml.dom.minidom`` and
        ``lxml.etree``. To use an alternative format, specify the name of
        a treebuilder:
        
        .. code-block:: python
        
          import html5lib
          with open("mydocument.html", "rb") as f:
              lxml_etree_document = html5lib.parse(f, treebuilder="lxml")
        
        When using with ``urllib2`` (Python 2), the charset from HTTP should be
        pass into html5lib as follows:
        
        .. code-block:: python
        
          from contextlib import closing
          from urllib2 import urlopen
          import html5lib
        
          with closing(urlopen("http://example.com/")) as f:
              document = html5lib.parse(f, transport_encoding=f.info().getparam("charset"))
        
        When using with ``urllib.request`` (Python 3), the charset from HTTP
        should be pass into html5lib as follows:
        
        .. code-block:: python
        
          from urllib.request import urlopen
          import html5lib
        
          with urlopen("http://example.com/") as f:
              document = html5lib.parse(f, transport_encoding=f.info().get_content_charset())
        
        To have more control over the parser, create a parser object explicitly.
        For instance, to make the parser raise exceptions on parse errors, use:
        
        .. code-block:: python
        
          import html5lib
          with open("mydocument.html", "rb") as f:
              parser = html5lib.HTMLParser(strict=True)
              document = parser.parse(f)
        
        When you're instantiating parser objects explicitly, pass a treebuilder
        class as the ``tree`` keyword argument to use an alternative document
        format:
        
        .. code-block:: python
        
          import html5lib
          parser = html5lib.HTMLParser(tree=html5lib.getTreeBuilder("dom"))
          minidom_document = parser.parse("<p>Hello World!")
        
        More documentation is available at https://html5lib.readthedocs.io/.
        
        
        Installation
        ------------
        
        html5lib works on CPython 2.7+, CPython 3.3+ and PyPy.  To install it,
        use:
        
        .. code-block:: bash
        
            $ pip install html5lib
        
        
        Optional Dependencies
        ---------------------
        
        The following third-party libraries may be used for additional
        functionality:
        
        - ``datrie`` can be used under CPython to improve parsing performance
          (though in almost all cases the improvement is marginal);
        
        - ``lxml`` is supported as a tree format (for both building and
          walking) under CPython (but *not* PyPy where it is known to cause
          segfaults);
        
        - ``genshi`` has a treewalker (but not builder); and
        
        - ``chardet`` can be used as a fallback when character encoding cannot
          be determined.
        
        
        Bugs
        ----
        
        Please report any bugs on the `issue tracker
        <https://github.com/html5lib/html5lib-python/issues>`_.
        
        
        Tests
        -----
        
        Unit tests require the ``pytest`` and ``mock`` libraries and can be
        run using the ``py.test`` command in the root directory.
        
        Test data are contained in a separate `html5lib-tests
        <https://github.com/html5lib/html5lib-tests>`_ repository and included
        as a submodule, thus for git checkouts they must be initialized::
        
          $ git submodule init
          $ git submodule update
        
        If you have all compatible Python implementations available on your
        system, you can run tests on all of them using the ``tox`` utility,
        which can be found on PyPI.
        
        
        Questions?
        ----------
        
        There's a mailing list available for support on Google Groups,
        `html5lib-discuss <http://groups.google.com/group/html5lib-discuss>`_,
        though you may get a quicker response asking on IRC in `#whatwg on
        irc.freenode.net <http://wiki.whatwg.org/wiki/IRC>`_.

        1.0
        ~~~
        
        Released and unreleased on December 7, 2017. Badly packaged release.
        
        
        0.999999999/1.0b10
        ~~~~~~~~~~~~~~~~~~
        
        Released on July 15, 2016
        
        * Fix attribute order going to the tree builder to be document order
          instead of reverse document order(!).
        
        
        0.99999999/1.0b9
        ~~~~~~~~~~~~~~~~
        
        Released on July 14, 2016
        
        * **Added ordereddict as a mandatory dependency on Python 2.6.**
        
        * Added ``lxml``, ``genshi``, ``datrie``, ``charade``, and ``all``
          extras that will do the right thing based on the specific
          interpreter implementation.
        
        * Now requires the ``mock`` package for the testsuite.
        
        * Cease supporting DATrie under PyPy.
        
        * **Remove PullDOM support, as this hasn't ever been properly
          tested, doesn't entirely work, and as far as I can tell is
          completely unused by anyone.**
        
        * Move testsuite to ``py.test``.
        
        * **Fix #124: move to webencodings for decoding the input byte stream;
          this makes html5lib compliant with the Encoding Standard, and
          introduces a required dependency on webencodings.**
        
        * **Cease supporting Python 3.2 (in both CPython and PyPy forms).**
        
        * **Fix comments containing double-dash with lxml 3.5 and above.**
        
        * **Use scripting disabled by default (as we don't implement
          scripting).**
        
        * **Fix #11, avoiding the XSS bug potentially caused by serializer
          allowing attribute values to be escaped out of in old browser versions,
          changing the quote_attr_values option on serializer to take one of
          three values, "always" (the old True value), "legacy" (the new option,
          and the new default), and "spec" (the old False value, and the old
          default).**
        
        * **Fix #72 by rewriting the sanitizer to apply only to treewalkers
          (instead of the tokenizer); as such, this will require amending all
          callers of it to use it via the treewalker API.**
        
        * **Drop support of charade, now that chardet is supported once more.**
        
        * **Replace the charset keyword argument on parse and related methods
          with a set of keyword arguments: override_encoding, transport_encoding,
          same_origin_parent_encoding, likely_encoding, and default_encoding.**
        
        * **Move filters._base, treebuilder._base, and treewalkers._base to .base
          to clarify their status as public.**
        
        * **Get rid of the sanitizer package. Merge sanitizer.sanitize into the
          sanitizer.htmlsanitizer module and move that to sanitizer. This means
          anyone who used sanitizer.sanitize or sanitizer.HTMLSanitizer needs no
          code changes.**
        
        * **Rename treewalkers.lxmletree to .etree_lxml and
          treewalkers.genshistream to .genshi to have a consistent API.**
        
        * Move a whole load of stuff (inputstream, ihatexml, trie, tokenizer,
          utils) to be underscore prefixed to clarify their status as private.
        
        
        0.9999999/1.0b8
        ~~~~~~~~~~~~~~~
        
        Released on September 10, 2015
        
        * Fix #195: fix the sanitizer to drop broken URLs (it threw an
          exception between 0.9999 and 0.999999).
        
        
        0.999999/1.0b7
        ~~~~~~~~~~~~~~
        
        Released on July 7, 2015
        
        * Fix #189: fix the sanitizer to allow relative URLs again (as it did
          prior to 0.9999/1.0b5).
        
        
        0.99999/1.0b6
        ~~~~~~~~~~~~~
        
        Released on April 30, 2015
        
        * Fix #188: fix the sanitizer to not throw an exception when sanitizing
          bogus data URLs.
        
        
        0.9999/1.0b5
        ~~~~~~~~~~~~
        
        Released on April 29, 2015
        
        * Fix #153: Sanitizer fails to treat some attributes as URLs. Despite how
          this sounds, this has no known security implications.  No known version
          of IE (5.5 to current), Firefox (3 to current), Safari (6 to current),
          Chrome (1 to current), or Opera (12 to current) will run any script
          provided in these attributes.
        
        * Pass error message to the ParseError exception in strict parsing mode.
        
        * Allow data URIs in the sanitizer, with a whitelist of content-types.
        
        * Add support for Python implementations that don't support lone
          surrogates (read: Jython). Fixes #2.
        
        * Remove localization of error messages. This functionality was totally
          unused (and untested that everything was localizable), so we may as
          well follow numerous browsers in not supporting translating technical
          strings.
        
        * Expose treewalkers.pprint as a public API.
        
        * Add a documentEncoding property to HTML5Parser, fix #121.
        
        
        0.999
        ~~~~~
        
        Released on December 23, 2013
        
        * Fix #127: add work-around for CPython issue #20007: .read(0) on
          http.client.HTTPResponse drops the rest of the content.
        
        * Fix #115: lxml treewalker can now deal with fragments containing, at
          their root level, text nodes with non-ASCII characters on Python 2.
        
        
        0.99
        ~~~~
        
        Released on September 10, 2013
        
        * No library changes from 1.0b3; released as 0.99 as pip has changed
          behaviour from 1.4 to avoid installing pre-release versions per
          PEP 440.
        
        
        1.0b3
        ~~~~~
        
        Released on July 24, 2013
        
        * Removed ``RecursiveTreeWalker`` from ``treewalkers._base``. Any
          implementation using it should be moved to
          ``NonRecursiveTreeWalker``, as everything bundled with html5lib has
          for years.
        
        * Fix #67 so that ``BufferedStream`` to correctly returns a bytes
          object, thereby fixing any case where html5lib is passed a
          non-seekable RawIOBase-like object.
        
        
        1.0b2
        ~~~~~
        
        Released on June 27, 2013
        
        * Removed reordering of attributes within the serializer. There is now
          an ``alphabetical_attributes`` option which preserves the previous
          behaviour through a new filter. This allows attribute order to be
          preserved through html5lib if the tree builder preserves order.
        
        * Removed ``dom2sax`` from DOM treebuilders. It has been replaced by
          ``treeadapters.sax.to_sax`` which is generic and supports any
          treewalker; it also resolves all known bugs with ``dom2sax``.
        
        * Fix treewalker assertions on hitting bytes strings on
          Python 2. Previous to 1.0b1, treewalkers coped with mixed
          bytes/unicode data on Python 2; this reintroduces this prior
          behaviour on Python 2. Behaviour is unchanged on Python 3.
        
        
        1.0b1
        ~~~~~
        
        Released on May 17, 2013
        
        * Implementation updated to implement the `HTML specification
          <http://www.whatwg.org/specs/web-apps/current-work/>`_ as of 5th May
          2013 (`SVN <http://svn.whatwg.org/webapps/>`_ revision r7867).
        
        * Python 3.2+ supported in a single codebase using the ``six`` library.
        
        * Removed support for Python 2.5 and older.
        
        * Removed the deprecated Beautiful Soup 3 treebuilder.
          ``beautifulsoup4`` can use ``html5lib`` as a parser instead. Note that
          since it doesn't support namespaces, foreign content like SVG and
          MathML is parsed incorrectly.
        
        * Removed ``simpletree`` from the package. The default tree builder is
          now ``etree`` (using the ``xml.etree.cElementTree`` implementation if
          available, and ``xml.etree.ElementTree`` otherwise).
        
        * Removed the ``XHTMLSerializer`` as it never actually guaranteed its
          output was well-formed XML, and hence provided little of use.
        
        * Removed default DOM treebuilder, so ``html5lib.treebuilders.dom`` is no
          longer supported. ``html5lib.treebuilders.getTreeBuilder("dom")`` will
          return the default DOM treebuilder, which uses ``xml.dom.minidom``.
        
        * Optional heuristic character encoding detection now based on
          ``charade`` for Python 2.6 - 3.3 compatibility.
        
        * Optional ``Genshi`` treewalker support fixed.
        
        * Many bugfixes, including:
        
          * #33: null in attribute value breaks XML AttValue;
        
          * #4: nested, indirect descendant, <button> causes infinite loop;
        
          * `Google Code 215
            <http://code.google.com/p/html5lib/issues/detail?id=215>`_: Properly
            detect seekable streams;
        
          * `Google Code 206
            <http://code.google.com/p/html5lib/issues/detail?id=206>`_: add
            support for <video preload=...>, <audio preload=...>;
        
          * `Google Code 205
            <http://code.google.com/p/html5lib/issues/detail?id=205>`_: add
            support for <video poster=...>;
        
          * `Google Code 202
            <http://code.google.com/p/html5lib/issues/detail?id=202>`_: Unicode
            file breaks InputStream.
        
        * Source code is now mostly PEP 8 compliant.
        
        * Test harness has been improved and now depends on ``nose``.
        
        * Documentation updated and moved to https://html5lib.readthedocs.io/.
