Remarks

Use the CorrectHtml method to process any required HTML code to make it valid, safe and compliant with the specified document type (via the HtmlEditorHtmlEditingSettings.AllowedDocumentType property): XHTML 1.0 Transitional, HTML5, or both. The resulting HTML code is always kept safe, since the method removes all potentially harmful code - unknown tags and attributes, script elements, client-side event handlers and URLs with script content. Automatic validation also helps to keep the HTML code validity by correcting invalid tag hierarchies and changing invalid attribute values.
