Re: x=something, y=somethinelse and z=crud all likely to fail - how do i wrap them up

[Veek. M]

Thanks guys: you've given me some good ideas - I really need to re-read 
the lxml docs for xpath. (basically trying to scrape ebay and score a 
mobo - ebaysdk doesn't work) Also need to google those principles :)  
thanks! (i knew one shouldn't overly rely on chained attribute lookups - 
didn't figure that had a name :))
