Looking up a stock quote

I have an XSL file that generates HTML from XML data. I have something in
the data that is called the CUSIP #. For those who dont know this is
something that is used to identify uniquely a stock name. I want to be able
to get the the CUSIP# from the xml and then go against some
database/website/source/something that will give me the stock quote for this
stock.

Any ideas? I have no clue where to start. The only thing I know is that I
have to use XSL and XML only to do this.

Thanks in advance and looking for ideas.

TP.
