解析凌乱的书签plist转换为xml

Question

我正在使用Skim pdf查看器。

您可以通过下拉菜单搜索书签：

我在another answer读到，Skim将它锁在一个plist中：

~/Library/Preferences/net.sourceforge.skim-app.skim.bookmarks.plist

所以我通过跟随blog post：

将此文件转换为xml文件

plutil -convert xml1 bookmarks.plist

请参阅下面的完整转储。

现在，我正在尝试处理这个xml而不会造成太大的麻烦。我尝试使用active_support并且能够挖掘并找到我的书签：

[3] pry(main)> require 'active_support/core_ext/hash/conversions'
=> true
[5] pry(main)> h = Hash.from_xml(File.read('bookmarks.plist'))
[39] pry(main)> h['plist']['dict']['array'].first['dict'].each {|h| puts "#{h['integer']} : #{h['string'].first}" }
0 : some info about foobar
386 : some important bookmark about migrations
389 : some important note about anatomy of migrations
158 : cat

有更好的方法吗？
