通过哈希值的阵列在Perl遍历一个哈希表

问题描述：

我有哈希值的哈希看起来像这样的数组：

I have an Array of Hashes in a Hash that looks like this:

$VAR1 = {
          'file' => [
                      {
                        'pathname' => './out.log',
                        'size' => '51',
                        'name' => 'out.log',
                        'time' => '1345799296'
                      },
                      {
                        'pathname' => './test.pl',
                        'size' => '2431',
                        'name' => 'test.pl',
                        'time' => '1346080709'
                      },
                      {
                        'pathname' => './foo/bat.txt',
                        'size' => '24',
                        'name' => 'bat.txt',
                        'time' => '1345708287'
                      },
                      {
                        'pathname' => './foo/out.log',
                        'size' => '75',
                        'name' => 'out.log',
                        'time' => '1346063384'
                      }
                    ]
        };

如何通过在一个循环中，这些文件项迭代，并访问其值？一样容易复制我@array = @ {$ {文件列表文件}}; ，所以我只有哈希的数组

How can I iterate through these "file entries" in a loop and access its values? Is it easier to copy my @array = @{ $filelist{file} }; so i only have an array of hashes?

答

无需复制：

foreach my $file (@{ $filelist{file} }) {
  print "path: $file->{pathname}; size: $file->{size}; ...\n";
}
