One possible way:

Record = Struct.new("Record", :name, :date, :name_again, :some_num,
:buy_link, :some_num2, :letters, :price)
records = []

doc = Hpricot(doc)
stuff = doc/"/table/tr/td"

elements = stuff.map { |elem| elem.inner_html }.each_slice(8) do |slice|
  records << Record.new(*slice)
end

p records.sort_by {|record| record.price.slice(1..record.size) }

Note that since I did not know the semantics of the table cells,
sometimes the Struct Record has some weird fields in it, but you get the
idea.


Also I am not 100% sure if the sort_by should not be done on to_f-d
prices (probably not due to rounding problems, but I wonder if there can
be some weird string issues, too).

HTH,
Peter
