I need help parsing out some text from a page with lxml. I tried beautifulsoup and the html of the page I am parsing is so broken, it wouldn't work. So I have moved on to lxml, but the docs are a little confusing and I was hoping someone here could help me.
Here is the page I am trying to parse, I need to get the text under the "Additional Info" section. Note, that I have a lot of pages on this site like this to parse and each pages html is not always exactly the same (might contain some extra empty "td" tags). Any suggestions as to how to get at that text would be very much appreciated.
Thanks for the help.

import lxml.html as lh
import urllib2
def text_tail(node):
yield node.text
yield node.tail
url='http://bit.ly/bf1T12'
doc=lh.parse(urllib2.urlopen(url))
for elt in doc.iter('td'):
text=elt.text_content()
if text.startswith('Additional Info'):
blurb=[text for node in elt.itersiblings('td')
for subnode in node.iter()
for text in text_tail(subnode) if text and text!=u'\xa0']
break
print('\n'.join(blurb))
yields

Edit: Here is an alternate solution based on Steven D. Majewski's xpath which addresses the OP's comment that the number of tags separating 'Additional Info' from the blurb can be unknown:
import lxml.html as lh
import urllib2
url='http://bit.ly/bf1T12'
doc=lh.parse(urllib2.urlopen(url))
blurb=doc.xpath('//td[child::*[text()="Additional Info"]]/following-sibling::td/text()')
blurb=[text for text in blurb if text != u'\xa0']
print('\n'.join(blurb))
