Question

The whitelist plugin for CKEditor adds sanitization rules to the dataProcessor dataFilter and htmlFilter. If an element is not in the whitelist, it is removed, along with any child nodes:

// console.log("Remove " + element.name);
// The element (as well as any content or children) is removed.
return false;

However, I want to preserve any content/children. Basically, I’d like this:

This is <u>really</u> important!

To become this:

This is really important!

NOT this:

This is important!

Answer 1

Change line 37 of whitelist/plugin.js. Instead of returning false, what removes entire element, write:

delete element.name;

This will remove element’s tags, but will leave the content.
