Can I convert an iOS Info.plist into a ruby Hash?

I need to exclude specific keys found in an Info.plist for my app if they are found in another Hash. Currently I can access individual keys in Info.plist like this

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

and I can get the "setting 4 text" string set at this key in the plist dictionary...

However, I want to be able to iterate over all keys of this MysettingsDict. Does anyone have a method to convert an iOS XML plist to a ruby Dictionary?
