从perl哈希结构中获取数据？

Question

我正在尝试修改现有的perl脚本以支持地理编码.找到了这个模块:http://metacpan.org/pod/Geo :: Coder :: Google

我只是无法弄清楚如何从它返回的哈希结构中提取数据(我不是一个perl编码器,这只是我必须解决的一些遗留脚本).

       {
        '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
          ]
        }
      }

尝试过我在google上找到的所有哈希教程,我能用它打印的最多就像HASH(0x91e5558).到目前为止,我的代码是模块显示的示例:

use Geo::Coder::Google;
my $geocoder = Geo::Coder::Google->new(apikey => 'Your API Key');
my $location = $geocoder->geocode( location => 'Hollywood and Highland, Los Angeles, CA'); 

我只想要Point - >坐标数据到它自己的变量然后我可以写入数据库.

这是你想要的吗？

$lon = $location->{Point}{coordinates}[0];
$lat = $location->{Point}{coordinates}[1];
