<div class="block">The whitelist based HTML cleaner. Use to ensure that end-user provided HTML contains only the elements and attributes
that you are expecting; no junk, and no cross-site scripting attacks!
<p>
The HTML cleaner parses the input as HTML and then runs it through a white-list, so the output HTML can only contain
HTML that is allowed by the whitelist.
</p>
<p>
It is assumed that the input HTML is a body fragment; the clean methods only pull from the source's body, and the
canned white-lists only allow body contained tags.
</p>
<p>
Rather than interacting directly with a Cleaner object, generally see the <code>clean</code> methods in <a href="../../../org/jsoup/Jsoup.html" title="class in org.jsoup"><code>Jsoup</code></a>.
