<p>Instances cleans the document of each of the possible offending

override attributes in a subclass, or set them in the constructor.</p>
<dl class="rst-docutils">

<dt><tt class="rst-docutils literal">style</tt>:</dt>
<dd>Removes any style tags.</dd>

<dt><tt class="rst-docutils literal">forms</tt>:</dt>
<dd>Removes any form tags</dd>
<dt><tt class="rst-docutils literal">annoying_tags</tt>:</dt>

<dt><tt class="rst-docutils literal">remove_tags</tt>:</dt>
<dd>A list of tags to remove. Only the tags will be removed,
their content will get pulled up into the parent tag.</dd>
<dt><tt class="rst-docutils literal">kill_tags</tt>:</dt>
<dd>A list of tags to kill. Killing also removes the tag's content,
i.e. the whole subtree, not just the tag itself.</dd>
<dt><tt class="rst-docutils literal">allow_tags</tt>:</dt>
<dd>A list of tags to include (default include all).</dd>
<dt><tt class="rst-docutils literal">remove_unknown_tags</tt>:</dt>
<dd>Remove any tags that aren't standard parts of HTML.</dd>
<dt><tt class="rst-docutils literal">safe_attrs_only</tt>:</dt>
<dd>If true, only include 'safe' attributes (specifically the list
from the feedparser HTML sanitisation web site).</dd>
<dt><tt class="rst-docutils literal">safe_attrs</tt>:</dt>
<dd>A set of attribute names to override the default list of attributes
considered 'safe' (when safe_attrs_only=True).</dd>
<dt><tt class="rst-docutils literal">add_nofollow</tt>:</dt>
<dd>If true, then any <a> tags will have <tt class="rst-docutils literal"><span class="pre">rel="nofollow"</span></tt> added to them.</dd>
<dt><tt class="rst-docutils literal">host_whitelist</tt>:</dt>
<dd><p class="rst-first">A list or set of hosts that you can use for embedded content
(for content like <tt class="rst-docutils literal"><object></tt>, <tt class="rst-docutils literal"><link <span class="pre">rel="stylesheet"></span></tt>, etc).
You can also implement/override the method
<tt class="rst-docutils literal">allow_embedded_url(el, url)</tt> or <tt class="rst-docutils literal">allow_element(el)</tt> to
implement more complex rules for what can be embedded.
Anything that passes this test will be shown, regardless of
the value of (for instance) <tt class="rst-docutils literal">embedded</tt>.</p>
<p>Note that this parameter might not work as intended if you do not
make the links absolute before doing the cleaning.</p>
<p class="rst-last">Note that you may also need to set <tt class="rst-docutils literal">whitelist_tags</tt>.</p>
</dd>
<dt><tt class="rst-docutils literal">whitelist_tags</tt>:</dt>
<dd>A set of tags that can be included with <tt class="rst-docutils literal">host_whitelist</tt>.
The default is <tt class="rst-docutils literal">iframe</tt> and <tt class="rst-docutils literal">embed</tt>; you may wish to
include other tags like <tt class="rst-docutils literal">script</tt>, or you may want to
implement <tt class="rst-docutils literal">allow_embedded_url</tt> for more control. Set to None to
include all tags.</dd>
