it would be usefull to provide "hide selector, if contain selector".
Indeed, some website like Facebook use same class and structure for post and ads.
To handle this, we need to hide block, if it contain another selector or raw string.
Example:
Code: Select all
<article class="art">
<div class="tohide">Hide me !</div>
</article>
<article class="art">
<div class="tokeep">Don't hide me !</div>
</article>
