Getting values from hash

I am having problems accessing the element name of the trend. I don't know how to do it I tried

for my $search ( @{$result->{trends}} ) but I get the error "Not a HASH reference"

$VAR1 = [
          {
            'locations' => [
                             {
                               'woeid' => 1,
                               'name' => 'Globales'
                             }
                           ],
            'created_at' => '2012-04-26T13:42:24Z',
            'trends' => [
                          {
                            'events' => undef,
                            'query' => '%22A%20Picture%20Of%20Me%20Whe
+n%20I%20Was%22',
                            'promoted_content' => undef,
                            'name' => 'A Picture Of Me When I Was',
                            'url' => 'http://twitter.com/search/%s%22'
                          },                         
                        ],
            'as_of' => '2012-04-26T13:46:47Z'
          }
        ];

`$result` is not a hash reference. It's an array reference, note the outermost square brackets. Access first the array index, then the hash key, thus: `for my $search (@{ $result->[0]{trends} })` [download]	[reply] [d/l]

Say it with me, hashes are { curly }arrays are [ square ] $result is an array	[reply]

If a variable isn't the type you expect it to be, try to simply `print` it; your `$result` would look something like `ARRAY(0x62a964)`. -- Time flies when you don't know what you're doing	[reply] [d/l] [select]

The ref() command will help you to find out what type of reference you are referring to. Example: `$result = ['a','b','c','d']; print ref($result);` [download] This will print as "ARRAY".	[reply] [d/l]
