title: Using rvest to scrape a website - Selecting html node?
body: <p>I have a question about my latest r vest scrape.</p>
  
  <p>I want to scrape this page (and some other stocks as well):
  <a href="http://www.finviz.com/quote.ashx?t=AA&amp;ty=c&amp;p=d&amp;b=1" rel="nofollow noreferrer">http://www.finviz.com/quote.ashx?t=AA&amp;ty=c&amp;p=d&amp;b=1</a></p>
  
  <p>I need a list of the Market Capital, which is the first box in the second line.
  This list should contain approx 50-100 stocks.</p>
  
  <p>I am using rvest for that.</p>
  
  <pre><code>library(rvest)
  
  html = read_html("http://www.finviz.com/quote.ashx?t=A")
  
  cast = html_nodes(html, "table-dark-row")
  </code></pre>
  
  <p>The problem is, I can not get around the html_nodes.
  Any idea about how to find out the correct node for the html_nodes?</p>
  
  <p>I am using firebug/firefinder to check out the webpage.</p>
