SyntaxError: JSON.parse: unexpected character

Answer 1

What exactly are you trying to parse? The whole response won't parse because it's XML, not json. If you are trying to parse just the value of the string element then you probably need to wrap it in quotes.
Update:
JSON.parse('[{"Title":"SQL","ReleaseDate":"\/Date(1224007200000)\/"},{"Title":"Termonator Salvation","ReleaseDate":"\/Date(1224007200000)\/"}]')
