Moodle 1.5 has a HTML "Tidy" filter. It checks if the HTML code in Moodle is XHTML compliant. I could not find any documentation how the filter works. I activated it but did not see any changes in the HTML Editor or it's output.
Text, that is edited several times with the HTML Editor becomes quite unpredictable how it will be rendered in the different browsers. It would be great if the Tidy filter can clean up the text automatically or help the writer to do so.
Can please anybody explain the filter or give me a link, how it works in Moodle?
