|
|
|
|
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, 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, 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!")
|
|
|
|

|
Installation
|
|
------------
|
|
|
|
html5lib works on CPython 2.6+, CPython 3.2+ 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 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
|
|
|
|
- ``charade`` can be used as a fallback when character encoding cannot
|
|
be determined; ``chardet``, from which it was forked, can also be used
|
|
on Python 2.
|
|
|
|
- ``ordereddict`` can be used under Python 2.6
|
|
(``collections.OrderedDict`` is used instead on later versions) to
|
|
serialize attributes in alphabetical order.
|
|

Bugs
|
|
----
|
|
|
|
Please report any bugs on the `issue tracker
|
|
<https://github.com/html5lib/html5lib-python/issues>`_.
|
|
|
|
|
|
Tests
|
|
-----
|
|
|
|
Unit tests require the ``nose`` library and can be run using the
|
|
``nosetests`` command in the root directory; ``ordereddict`` is
|
|
required under Python 2.6. All should pass.
|
|
|
|
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.

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 http://html5lib.readthedocs.org/.
