I have a use-case where I need to specify the URL to a generated CSS file within a Javascript options object. I therefore need the publicPath without the HTML tags.

I have created a working implementation here but maybe there is a better way to do it.

I am using the new tag in the CKeditor config. 'editor' is the name of the CSS bundle:

CKEDITOR.config.contentsCss = '{% bundle_item_url 'editor' 'css' %}';
