我可以将 iOS Info.plist 转换为 ruby​​ Hash 吗？

Question

如果在另一个哈希中找到特定键，我需要排除在我的应用程序的 Info.plist 中找到的特定键。目前我可以像这样访问 Info.plist 中的各个键

setting4Str = `/usr/libexec/PlistBuddy -c \"print :MySettingsDict:setting4" {settings_file}`

我可以在 plist 字典中的这个键上设置“设置 4 文本”字符串......

但是，我希望能够遍历此 MysettingsDict 的所有键。有没有人有将 iOS XML plist 转换为 ruby​​ 字典的方法？

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

添加给那些想要解析二进制Info.plist 的人。

info_plist = File.read("Info.plist") # read binary plist
IO.popen('plutil -convert xml1 -r -o - -- -', 'r+') {|f|
  f.write(info_plist)
  f.close_write
  info_plist = f.read # xml plist
}

现在 info_plist 是一个 xml 字符串。要快速提取一个属性，您可以使用正则表达式：

app_bundle = info_plist.scan(/<key>CFBundleIdentifier<\/key>\s+<string>(.+)<\/string>/).flatten.first

或者解析xml并转换为hash。
