Perlより、シンプルに書けるみたいだ。
require 'open-uri'
require 'nkf'
url = "http://bokete.jp/user/kamadango/boke";
content = open(url).read
content = NKF.nkf("-w", content)
counts = content.scan(/★の合計.*?(\d+)/).map { |x| x[0] }
total = 0
counts.each { |count|
total += count.to_i
}
print "total: " + total.to_s + "\n";
