こんにちは、 URL-ENCODING 、 %3A 、 %2F を含む文字列があります ...

http%3A%2F%2Fmydomain.com%2Fimage%2Fflv%2F1%2F8%2Fa%2Fimage_18060.jpg%3Fe%3D13777194

「特殊文字」 http://www.w3schools.com/tags/ref_urlencode.aspをASCII文字に置き換えたいのですが、Railsでプログラミングしていますが、どこから始めればよいかわかりません。あなたはなにか考えはありますか？

ご助力ありがとうございます！

うーん、このように URI.unescape を使用できますか?

scraper = Scraper.define do
    array :items
    process "div.mozaique>div", :items  => Scraper.define {
      process "div.thumb>a", URI.unescape(:link) => "@href"
      result :link
    }
    result :items
  end
