Hi Hari

An Article on the O'Reilly Network about consuming a Yahoo REST web service should help to get you started. The article desribes how to make a request and how to parse the xml :

http://www.oreillynet.com/pub/a/network/2005/02/28/yahoo.html

The important part looks like this :

# Make the request
my $yahoo_response = get($req_url);

# Parse the XML
my $xmlsimple = XML::Simple->new();
my $yahoo_xml = $xmlsimple->XMLin($yahoo_response);


The article does not cover url encoding. If you use one of the geonames services whith a placename as parameter you have to url encode the placename before constructing the final url:

use URI::Escape;
$escapedParameter = uri_escape("new york");


Hope this helps.
