Data parsing from websites

I need the following data parsed from this website: [login to view URL] Every podcast needs to be parsed, with the following information: { "entries": [ { "description": "It's a very special edition of Oh! today as Chris and Greg try to work out which mystery liquid is Scott's Special Sample. Also, the usual Friday stuff, including One Direction opening a meat shop, some fuge news and Scott potentially going to prison for spending too long on a roundabout.", "downloadURL": "[login to view URL]'s%20Special%20Sample%2011%[login to view URL]", "name": "Scott's Special Sample - 11th May 2012" }, ...... ] } The final result must be a script that can do this parsing. The generated JSON from this script must be validated via: [login to view URL] NOTE: Every page must be parsed, not just the initial page posted.
