  • - Tags with no attributes and no content, and that are not empty - elements (remove <a></a> but not - <br />), and -

-

- 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. -

-

- 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. -

- Prior to HTML Purifier 3.1.1, this directive also enabled the munging - of browsable external resources, which could break things if your redirection - script was a splash page or used meta tags. To revert to - previous behavior, please use %URI.MungeResources. -

- You may want to also use %URI.MungeSecretKey along with this directive - in order to enforce what URIs your redirector script allows. Open - redirector scripts can be a security risk and negatively affect the - reputation of your domain name. -
