As a general thing we would rather see you include the minimum data required to along with your node. Linking to data elsewhere has the issue that the linked data may change, be removed or move. In this case your link seems to be broken.

If you would like further help with this issue I suggest you mock up a very small data set (no more than a few dozen lines of text) for us to play with. It also helps if you can indicate the type of output expected from running the script against your sample data set so we know what we are aiming at.
