Parsing website with Hpricot

Question

I'm trying to parse images from reddit using Ruby and the Hpricot gem.

Using Chrome I got the XPath to the div holding the link to the image then I use doc.search to find it but the results come up empty.

doc.search('//*[@id="siteTable"]/div[1]/a').each do |r|
    puts r.attributes['href']
end

Any ideas?
