I am allowing users to imput HTML code into a textarea. After they input this, I wany to output their HTML to the browser. In order for the document to be safe, I need to close all open HTML tags that have been left open by the user, along with any open comments. Is there a way to take an HTML string and add closing tags and comments to it if needed?I would use a regular expression to grab the valid opening and closing HTML tags, and use something á la htmlentities() on the rest of the document.
Thanks,
Matt
