Subject: problem with .each do

Hiya.  The book does things this way, so why doesn't it work for me? 
What's going on?

def fromWeb(site, url)
	# get data from website
	h = Net::HTTP.new(site, 80)
	resp, data=h.get(url, nil)

	# process data
	data.each do <- point of second error
		|line|
		if /DGM_navigation/ =~ line do
			# decode page lineage
			step=Array.new
			astep, line = getNextWord(line)
			while astep != nil
				step.push(astep)
				astep, line = getNextWord(line)
			end
			puts "Page Lineage"
			step.each do
				|astep|
				step.each do
					put " "
				end
				puts astep
			end
		end # end DGM_naviation
	end # end data.each <- gets "undefined method 'line'", from the second 
error point above
end # end def fromWeb

def getNextWord(line)
	i1 = />\w+</ =~ line

	string_wanted=$&[1..$&.length-1]
	string_remaining=$'
	return string_wanted, string_remaining
end
