使用Ruby从公共Google日历中获取数据

I want to download and parse all the event data from a website's public google calendar, what would be the best way to do so? I'm considering just downloading the ics file or getting xml data and parsing that myself. I've looked into google api but it looks unnecessarily complex if all I want to do is read the data. I'm a beginner to working with API's and programming in general so I'm having trouble navigating all that documentation. They don't provide very many helpful examples.
