CSS/jQuery selector to find elements which don't have a certain parent

I found solutions to check if the parent does not have a certain class using :parent, but I want to have a node type excluded. In my case I only wants forms which are not placed withing an article.

I found a solution with filter, but I was wondering if there is a selector only way to achieve the same:

$('form.frm').filter(function() {

    return $(this).parent().is(":not(article)");

});

EDIT: This solution isn't perfect as it only works if the form.frm is an immediate child of article. Sometimes I have a div in between.
Here a simplified DOM structure:

<div id="pageContent">

    <articel>

        <div class="box">

            <form class="frm"></form>

        </div>

    </article>

    <articel>

        <form class="frm"></form>

    </article>

</div>

Whats the parent of article element? Would be great if you can share relevant DOM

You can produce a list of all elements that are not a child of an article. querySelectorAll(':not(article)>*') but you really mean a list of all elements that are not a descendant of an article, right?

Answer is a modification of Mohammad's. The difference is that this code is not using filter, it is using not:

$('form.frm').not('article form.frm')

This is more or less the same thing. You specify a global selector, then exclude the forms you do not want (in this case, any form that is a descendent of article).

$('form.frm').not('article form.frm').css('color', 'red');

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<div id="pageContent">

  <article>

    <div class="box">

      <form class="frm">article > div</form>

    </div>

  </article>

  <article>

    <form class="frm">article</form>

  </article>

  <div class="box">

    <form class="frm">div</form>

  </div>
