AutoFormat.RemoveEmpty TYPE: bool VERSION: 3.2.0 DEFAULT:
false --DESCRIPTION-- <p> When enabled, HTML Purifier will
attempt to remove empty elements that contribute no semantic information
to the document. The following types of nodes will be
removed: </p> <ul><li> Tags with no attributes and
no content, and that are not empty elements (remove
<code>&lt;a&gt;&lt;/a&gt;</code> but not
<code>&lt;br /&gt;</code>), and </li>
<li> Tags with no content, except for:<ul>
<li>The <code>colgroup</code> element, or</li>
<li> Elements with the <code>id</code> or
<code>name</code> attribute, when those attributes are
permitted on those elements. </li>
</ul></li> </ul> <p> Please be very careful
when using this functionality; while it may not seem that empty elements
contain useful information, they can alter the layout of a document
given appropriate styling. This directive is most useful when you are
processing machine-generated HTML, please avoid using it on regular user
HTML. </p> <p> Elements that contain only whitespace will
be treated as empty. Non-breaking spaces, however, do not count as
whitespace. See %AutoFormat.RemoveEmpty.RemoveNbsp for alternate
behavior. </p> <p> This algorithm is not perfect; you may
still notice some empty tags, particularly if a node had elements, but
those elements were later removed because they were not permitted in
that context, or tags that, after being auto-closed by another tag,
where empty. This is for safety reasons to prevent clever code from
breaking validation. The general rule of thumb: if a tag looked empty on
the way in, it will get removed; if HTML Purifier made it empty, it will
stay. </p> --# vim: et sw=4 sts=4
