public class Cleaner extends Object
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.
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.
Rather than interacting directly with a Cleaner object, generally see the
