Getting a comic from For Better or for Worse

The HTML below is a sample of what we need to screen scrape for to find the a comic from For Better or for Worse

We need to find the div with a class of 'entry-content' and then get the next image. There is only one such use of the class in the HTML.

<div class="entry-content">
    <p>
        <img src="/strip_fix/strips/fb_c140530.gif" alt=""></img>
    </p>
