The code was just a snippet of some other code I have, but in regards to your points:
1. There are only 3 points where errors can creep in that I see:
1- if the urlopen fails or
2- during the htmlparser() if the html is super-malformed (same w/ BeautifulSoup).
3- if google changes their html format(but that will screw up almost any scraper)
The xpath and rest of the code will be work without problem since xpath will return '' if the xpath fails.
4. If you change the line:
then lxml handles malformed html almost as well as BeautifulSoup.
Anyways, I enjoy your blog, and just thought that I'd throw that out there.

For example, <pre lang="python">...</pre> will insert Python highlighted code.
* use <code>...</code> to highlight a variable or a single shell command.
* use <a href="url" nospam>title</a> to insert links.
<a href="url" nospam>title</a>
