How to implement NITF 2.5 Feed?

["lurker003" <ben@uktrader.net>]

Apologies in advance in this is a very basic question but I'm an 
absolute XML newbie.

I've just been approved to display an XML News Feed on my side. They 
sent me a link to a page of .xml headline files with the following 
explanation -

The newsfeed is updated three time a day at 6:55am (main from the 
days paper), 12:55 & 6:55pm (latest news headlines for the day). 
These files are provided on an "as is" basis. We cannot provide any 
additional assistance in getting these displayed on your site. 

The feed format is in NITF 2.5 XML. 

Each file represents a headline and link. These have a news category 
and subcategory detailed under the "tobject". The key field 
is "subect type" which you will find broken down into our main news 
categories being: 

Ø        News 
Ø        Business 
Ø        Sport 
Ø        Technology 
Ø        Entertainment 
Ø        Travel 
Ø        Money 
Ø        Property 
Ø        Motoring 
Ø        Employment 

You will find that the "subject matter" does carry a sub category in 
some cases, eg: 
Ø        World (sub of News) 
Ø        Rugby, netball, league, cricket, etc (sub of sports) 
Ø        Economy, markets, agriculture, etc, (sub of Business) 

Can someone please tell me how I implement this feed on my site? 
Some example code would be gratefully received!

Thanks in anticipation,
Lurker
