shipping rating with Ups API
===

I'd like to make a small application (in PHP) to calculate the rating for UPS shipping but I can't understand how to reach the XML file containing the prices and other data.
I'd like to access the file with the url and then use the values with SimpleXML, like I can do with Geonames http://api.geonames.org/findNearbyPostalCodes?postalcode=8775&country=CH&radius=10&username=demo&style=full

Thanks!
