Add cleaned up, reformatted example xml

Hi Reuben, 

I've added a slightly cleaned of the sample xml output, so it's a slightly more clear what information is in the `Nature_of_Work_description` node.

Because this appear to be basic html, I'm thinking it might be possible to parse the contents with something like [Beautiful Soup](http://www.crummy.com/software/BeautifulSoup/), add the structure back in, and store it somewhere, either in a database, or a load of flat files somewhere.
