How to use greasemonkey to selectively remove content from a website

The content I am trying to modify has a series of

entries, and within each of these are other
entries. There are no
tags to help here. What I want the script to do is inspect the content of each of these
entries and look for some text. This will be used to determine whether the whole '' entry is deleted/hidden or not. Is this possible? How?

Below is an example. There are several of these in the page, and I want to delete/hide the ones where the text inside the
<div class="foo bar">
tags say "Yes." So in this example, this whole thing would get deleted/hidden.

<div class="entry">

<div class="fooPhoto"><a href="Addfoo.jsp?tid=954102"><img class="person" src="" border="0" width="24" height="24" onerror="this.src='images/site/icons/dude.png'" title="Photo Unavailable" alt="Photo Unavailable" ></a></div>

<div class="fooAvg">4.7</div>

<div class="foo bar">Yes</div>

<div class="fooShare">
<a class="shareEmail" href="referral.jsp?sid=882&tid=954102&pgid=3">Share using email</a>

</div><!-- closes entry -->

For questions like this, post a link to the target page. Or, if that is really not possible, save the page to and link to that.

Anyway, the general answer to your question is not too hard with the jQuery contains() selector. Something like this will work:

// ==UserScript==
// @name     _Remove annoying divs
// @include  http://YOUR_SERVER/YOUR_PATH/*
// @require
// ==/UserScript==

/*--- Use the jQuery contains selector to find content to remove.
    Beware that not all whitespace is as it appears.
var badDivs = $("div div:contains('Annoying text, CASE SENSITIVE')");

badDivs.remove ();

//-- Or use badDivs.hide(); to just hide the content.

Update for the newly clarified question/code:

In your specific example, you would use this:

var badDivs = $("div.entry'Yes')");

badDivs.parent ().remove ();

Update for the site specified in the comments:
Note that there is no need to search for text because the site conveniently gives the key div a class of isHot or notHot.

// ==UserScript==
// @name     _Unless they're hot, they're not (shown).
// @include*
// @require
// ==/UserScript==

var badDivs = $("#ratingTable div.entry").has ("div.notHot");

badDivs.remove ();
