    This is not a self embedded R script - it doesn't state all required packages at the beginning. And then it errors on the XML file etc. Once you have that fixed, I might be able to help you more.

      I've meant the required libraries. It's OK, finishing my solution that completes faster than others and will upload it soon.

      Well, slightly disappointed with the choice of winning solution (in my experience having a solution with functions always gets more points) but congratulating the winner to use plain XML and some possible pausing between server requests. Still believe functions, using a while loop and working with JSON is more correct and easier to maintain/enhance.
