title: python lxml parsing html
body: <p>I am trying to parse a html document. It contains a couple of tables.
  I am able to find the correct table and get data from it using</p>
  
  <pre><code>for cell in doc.xpath('//table[@class="CE_13"]')[0]:
      for a in cell:
          print a.text_content()
  </code></pre>
  
  <p>Table consists of 6 columns.
  I need only the fifth column. 
  Is it possible to get all values in a dict (smth like: <code>{ column1 : values_of_clm1 ;column2 : values_of_clmn2; .....})</code> and how? and then read form dict or do you suggest a different solution?</p>
