Searching for an image element whose src contains a keyword, in an iFrame's HTML using jQuery
<p>I am digging deep into a page's DOM to manipulate a certain image attribute. I have a web page which contains an iFrame. The iFrame contains an image. The image has no id attribute so I am going to locate it using it's src. The src contains the unique keyword 'planet'. How do I locate this image using jQuery?</p>

<p><strong>ADDITION:</strong></p>

<p>I can't reference anything in the iFrame's DOM. Is there a special way to reference an element inside an iFrame?</p>

<p>Example: alert( $(myIframe).find('html').length ) reports 0, expecting 1.</p>
