It's often easier to simply go directly to what you want with XPath.
I'm not sure exactly what you want to extract, but try this:


require 'open-uri'
url="http://www.nasdaq.com/aspxcontent/shortinterests.aspx?
symbol=FRE&selected=FRE"
doc=Hpricot(open(url))
rqTable=doc.search("//table[@class='dataGrid']//td/text()")
puts rqTable.inspect
