Re^2: Expanding / flattening a structure

Apologies, you are right, here is a better example of the input:

my $struct = {
    fruit  => [qw( apple pear )],
    type    => [qw( farmed organic )],
    period  => {
      20050824 => {
        to  => ['new york', 'london', ],
      },
      20050825 => {
        to  => ['auckland', ],
      },
    }
  };
[download]

update: fixed first date [ -> {

Maybe: `# example structure my $struct = { fruit => [qw( apple pear )], type => [qw( farmed organic )], period => { 20050824 => [ to => ['new york', 'london' ], ], 20050825 => [ to => ['auckland' ], ], }, };` [download] Would be syntactically valid? But given the only attribute to the date is to, why not remove that layer? jdtoronto	[reply] [d/l]

two reasons for the 'to': 1) the token 'to' names the values in the result, e.g. I end up with this in the expanded array of hashes: `to => 'auckland',` [download] 2) also, this is just an example, in reality there are more values, e.g. `period => { 20050824 => { to => [ 'auckland', 'new york', ], transport => [ 'air', ] }, },` [download]	[reply] [d/l] [select]

Are you sure that your data structure is the most efficient way to store your data? Take a look at Re: How can I visualize my complex data structure?. Eric	[reply]

I think that $struct is already reasonable efficient? Did you have a recommendation for a better way to structure it?	[reply]
