XML to JSON

Thank you Mark. Between your guidance and flat-out guessing I've made it work. I will post the modified functions in a different thread if that can save anyone some effort.
Have one remaining issue. I want to add any included photos with the tweets, but the key I need is 5 nested arrays deep and that seems to cause a syntax error if you go more than 3 levels (2 dots)

What i need is:

tweet.entities.media.List(0).media_url

Is there a special way to handle this?

Thanks
