I've been using an import of http://www.nfl.com/liveupdate/scorestrip/ss.xml

There are times where I need the data to update to the next week of games, but it's still on previous week/current. For example it's still pulling week #1 data.
Is there another way I can run this importxml file to give me future weeks or the next week?

I had saw this on the week: http://www.nfl.com/ajax/scorestrip?s...ype=%s&week=%d seasonType can be PRE, REG, or POST. For reg or post, weeks go 1-22
So I Used: http://www.nfl.com/ajax/scorestrip?s...ype=REG&week=2

But I'm not sure how I can use that to import it into google docs for week 2 for example. Anyone with more knowledge on this could help?
