From: Faith Greenwood on 15 Feb 2010 02:17 I am trying to do some geocoding w/ geo::coder::google. It works fine but my problem is accessing the values in the hash. How can I return the coordinates (ie '-122.397323','37.778993',)? #here is the hash (as posted on CSPAN page for Geo::Coder::Google) ##Link for a more legible version: http://search.cpan.org/~miyagawa/Geo-Coder-Google-0.06/lib/Geo/Coder/Google.pm { 'AddressDetails' => { 'Country' => { 'AdministrativeArea' => { 'SubAdministrativeArea' => { 'SubAdministrativeAreaName' => 'San Francisco', 'Locality' => { 'PostalCode' => { 'PostalCodeNumber' => '94107' }, 'LocalityName' => 'San Francisco', 'Thoroughfare' => { 'ThoroughfareName' => '548 4th St' } } }, 'AdministrativeAreaName' => 'CA' }, 'CountryNameCode' => 'US' } }, 'address' => '548 4th St, San Francisco, CA 94107, USA', 'Point' => { 'coordinates' => [ '-122.397323', '37.778993', 0 ] } } ------------ my code is as follows: ... my $geocoder = Geo::Coder::Google->new(apikey=>'my_key'); my $location=undef; $location=$geocoder->geocode(location=>"548 4th St, San Francisco, CA 94107, USA"); while (my ($key,$value)=each(%$location)){ print "$key=>$value\n"; } ... #unfortunately, I am unable to get past this part and can't find anything w/in the module to help. thx!

Read perldoc perlreftut for an introduction to references. If $location contains the hashref above, then $location->{Point} is { 'coordinates' => [ '-122.397323', '37.778993', 0 ] } $location->{Point}{coordinates} is [ '-122.397323', '37.778993', 0 ] and finally, $location->{Point}{coordinates}[0] is '-122.397323', hp |
