將 del.icio.us 的 bookmarks 抓下來

簡單的利用 open-uri 及 REXML 讓我們把 del.icio.us 的 bookmarks 抓下來吧, 用 Ruby 還真是方便.

1. Ruby 記得要用 1.8.4 版本, 1.8.2 open-uri 有個 bug 不能用
2. 原始碼, 記得要換上你的帳號和密碼

require 'open-uri'
require 'rexml/document'

class Bookmark
 attr :user, :password
 attr_accessor :bookmarks

 def initialize(user, password)
   @user = user
   @password = password
 end

 def readit()
   open("http://del.icio.us/api/posts/all",
       "User-Agent" => "Ruby/#{RUBY_VERSION}",
       :http_basic_authentication=>[@user, @password]) do |f|
     #puts f.read
     d = REXML::Document.new(f.read)

     #
     @bookmarks = []
     d.elements.each("*/post") do |e|
       bookmark = {}
       bookmark["href"] = e.attributes['href']
       bookmark["description"] = e.attributes['description']
       bookmark["tag"] = e.attributes['tag'].split(' ').map {|t| t}
       bookmark["time"] = e.attributes['time']
       bookmark["hash"] = e.attributes['hash']
       @bookmarks << bookmark
     end
   end
  
   @bookmarks
 end
end

#
bk = Bookmark.new("user name", "password")
bk.readit().each do |i|
 puts "#{i["href"]} #{i["tag"]}"
end
