Is it possible to hide elements that are above a matched html comment using jQuery?

Question

I have a weird sort of use-case where our blogging tool appends a <!-- Read More --> into a post and anything above that gets pushed to our listing page.

What I want to do is find the matching comment, then tell any <p> tag above it (in the DOM) should be set to .hide() or .remove() . Here is what I have started, I'm not quite sure if I can select a .prevAll on an HTML comment.

var content = $('.main').html();
//search for matching comment
var comment = content.match(/<!--.*?-->/);
alert(comment);
comment.prevAll('p').remove();

You can see my fiddle here.

Is there anyway to go about accomplishing this task?

You could get any comments filtering nodeType and checking for specific value, eg:

 //find read more comment $('*').contents().filter(function() { return this.nodeType === 8 && this.nodeValue.trim() === "Read More"; }).prevAll('p').hide(); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div class="main"> <p> jhkdsjhjlasfkdldfasdfd </p> <div> no-hide </div> <p> jhkdsjhjlasfkdldfasdfd </p> <!-- Read More --> <p> dfasfsfkljfaskf;sa </p> <!-- test --> </div>
