Passing more than one latitude,longitude in a url for reverse geocoder

Hi all

I'm a newbie in GIS, so don't know much about it One of the first things I'm trying to accomplish is this:

I have a a list of latitude,longitude and I need to validated them I found this url (webservice) http://nominatim.openstreetmap.org/reverse?format=xml&lat=52.5487429714954&lon=-1.81602098644987&zoom=1&addressdetails=-1

As you can see I can pass only one latitude,longitude. It is possible to pass a list of latitude,longitude to process them all at once? is there any procedure that I can use to do this? probably CURL

I really appreciate any guidance on this one.

Thanks in advance
