title: Get value from lxml.etree._Element
body: <p>Having the following:</p>
  
  <pre><code>from lxml import html
  import io
  from lxml import etree
  
  parser = etree.HTMLParser() 
  doc   = etree.parse(io.FileIO("index.html"), parser)
  i=1
  
  total = []
  
  aa = doc.xpath(".//body/table[10]")
  for x in aa:
      for j in x:
          for k in j:
              print type(k) #output is &lt;type 'lxml.etree._Element'&gt;
              print k.text
  </code></pre>
  
  <p>Part of html file:</p>
  
  <p><a href="http://pastebin.com/2eftj9qL" rel="nofollow">http://pastebin.com/2eftj9qL</a></p>
  
  <p>This will display:</p>
  
  <pre><code>/Request_number_1
  15

  100.00%
  1035 ms
  923 ms
  1407 ms

  100.00%
  966 ms
  857 ms
  1613 ms

  </code></pre>
  
  <p>How can I iterate trough this lxml element? I want to retrieve the first value expressed in milliseconds (ex. average_time_array = [1035 ms, 966ms])  </p>
