title: Scraperwiki + lxml. How to get the href attribute of a child of an element with a class?
body: <p>On the link that contains 'alpha' in the URL has many links(hrefs) which I would like to collect from 20 different pages and paste onto the end of the general url(second last line). The href are found in a table which class is mys-elastic mys-left for the td and the a is obviously the element which contains the href attribute. Any help would greatly be appreciated for I have been working at this for about a week.</p>
  
  <pre><code>for i in range(1, 11):
  # The HTML Scraper for the 20 pages that list all the exhibitors
   url = 'http://ahr13.mapyourshow.com/5_0/exhibitor_results.cfm?alpha=%40&amp;type=alpha&amp;page='         + str(i) + '#GotoResults'
  print url
  list_html = scraperwiki.scrape(url)
  root = lxml.html.fromstring(list_html)
  href_element = root.cssselect('td.mys-elastic mys-left a')
  
  for element in href_element:
  #   Convert HTMl to lxml Object 
   href = href_element.get('href')
   print href
  
   page_html = scraperwiki.scrape('http://ahr13.mapyourshow.com' + href)
   print page_html
  </code></pre>
