HTML tidy filter
Notice: Moodle Docs will be switched to read-only mode starting on Tuesday 17 October 14:00 UTC for server maintenance. The estimated read-only period should not take more than 24 hours.
This filter checks whether HTML code is XHTML compliant, tidying where necessary. To make this filter work you need to have PHP compiled with the libtidy option; see http://www.php.net/tidy.
