I could use some help in understanding XMLTV

There are many large holes in my knowledge and understanding of Linux, MythTV, MYSQL, XML, XMLTV and Schedules Direct. 

Since last September I have been obtaining schedule information for 21 UK Freeview channels with commands like this "wget http://xmltv.radiotimes.com/xmltv/2047.dat" but metabroadcast.com has now shut down this service. All I need is the raw schedule data. I don't need or want to import it into any popular application. I can write Paradox Objectpal code to convert the data into a more readable database structure which works well for what I need. 

Is it possible that I can use XMLTV for this purpose and, if so, how?

I would appreciate some advice on what is possible, what is permitted and some help with implementation.

I am currently running MythTV 0.27 on Lubuntu 13.10 and I run Paradox 7 either via Wine on Zorin 9 or on Windows XP Pro SP2.
