Read google public calendar

I need to read the RSS feed of google Calendar.开发者_如何学运维 It is publicly available in a site.

How get the events of calendar through RSS feed?

Sample Using Google Calendar API JSON Output

http://www.google.com/calendar/feeds/developer-calendar@google.com/public/full?alt=json-in-script&callback=insertAgenda&orderby=starttime&max-results=15&singleevents=true&sortorder=ascending&futureevents=true

This retrieves the full projection of the public feed for the developer-calendar@google.com calendar in JSON format (alt=json-in-script) with a callback function called insertAgenda. A maximum of 15 events is returned (max-results=15), recurring events are represented as individual events (singleevents=true) and all events in the future (futureevents=true) are returned in ascending order (sortorder=ascending).
