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><a></a></code> but not + <code><br /></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 |
