hi ...

as far as i understand the user could enter code in a textarea and you want to make a kind of preview and show the entered code directly in the browser? ... so now you want to avoid any execution of js that the user entered with his code?

first you could delete any <script>-nodes from the code ... in case it woud be coded into the handler-attributes it is a little bit more work ... you have to remove all that attributes and its values or overwrite it ... i think this would be the best way ... since i think the code should be stored in a DB later on?

kind regards
