title: How to get these values with BeautifulSoup?
body: <p>I have this html table:</p>
  
  <pre><code>&lt;table&gt;
      &lt;tr&gt;
          &lt;td class="datax"&gt;a&lt;/td&gt;
          &lt;td class="datax"&gt;b&lt;/td&gt;
          &lt;td class="datax"&gt;c&lt;/td&gt;
          &lt;td class="datax"&gt;d&lt;/td&gt;
      &lt;/tr&gt;
      &lt;tr&gt;
          &lt;td class="datax"&gt;e&lt;/td&gt;
          &lt;td class="datax"&gt;f&lt;/td&gt;
          &lt;td class="datax"&gt;g&lt;/td&gt;
          &lt;td class="datax"&gt;h&lt;/td&gt;
      &lt;/tr&gt;
  &lt;/table&gt;
  </code></pre>
  
  <p>How to get the second and the fourth value of each <code>&lt;tr&gt;</code> ?
  If i do:</p>
  
  <pre><code>bs.findAll('td', {'class':'datax'})
  </code></pre>
  
  <p>I get:</p>
  
  <pre><code>        &lt;td class="datax"&gt;a&lt;/td&gt;
          &lt;td class="datax"&gt;b&lt;/td&gt;
          &lt;td class="datax"&gt;c&lt;/td&gt;
          &lt;td class="datax"&gt;d&lt;/td&gt;
  
          &lt;td class="datax"&gt;e&lt;/td&gt;
          &lt;td class="datax"&gt;f&lt;/td&gt;
          &lt;td class="datax"&gt;g&lt;/td&gt;
          &lt;td class="datax"&gt;h&lt;/td&gt;
  </code></pre>
  
  <p>it's correct! but I would like to have this result:</p>
  
  <pre><code>        &lt;td class="datax"&gt;b&lt;/td&gt;
          &lt;td class="datax"&gt;d&lt;/td&gt;
  
          &lt;td class="datax"&gt;f&lt;/td&gt;
          &lt;td class="datax"&gt;h&lt;/td&gt;
  </code></pre>
  
  <p>so, the values I want are -> <strong>b - d - f - h</strong></p>
  
  <p>(the second and the forth <code>&lt;td&gt;</code> of each <code>&lt;tr&gt;</code>)</p>
  
  <p>Is it possible with BeautifulSoup module?</p>
  
  <p>Thank you very much!</p>
