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><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
