title: Need help with XPATH for src value of a specific Html img tag
body: <p>I am somewhat new to XPATH and understand most of the basics, but I am having some trouble with a particular query.</p>
  
  <p>I am attempting to parse a Motley Fool page and return the source of the image for the caps score of a stock.</p>
  
  <p>For example: if you look at the source for the page: <a href="http://caps.fool.com/Ticker/SLT.aspx" rel="nofollow">http://caps.fool.com/Ticker/SLT.aspx</a> I want the source for <a href="http://g.foolcdn.com/art/ratings/stars/trans/5stars-trans-lg.png" rel="nofollow">http://g.foolcdn.com/art/ratings/stars/trans/5stars-trans-lg.png</a></p>
  
  <p>I only want what follows the src= if possible.</p>
  
  <p>I am currently working with:</p>
  
  <pre><code>xpath = "//div[@class='subtle marginT']"
  </code></pre>
  
  <p>This however is returning nothing. I know it might be asking a lot, but if you feel like answering, I would also greatly appreciate a quick reasoning for the answer as I want to learn XCAP, not just get this query to work.</p>
