hpricot：Hpricot::Elements：Getting More Detailed

マニュアルだと、

doc.search("h3").each do |h3|
  while ele = h3.next_sibling
    ary << ele   # stuff away all the elements under the h3
  end
end

となっているが、これはうまく動くのか？

ary = []
doc.search("h3").each do |h3|
  ele = h3
  while ele = ele.next_sibling
    ary << ele
  end
end

の間違いかとも思ったが、それでも変っぽい
