Hello all,
I'm trying to sort on a nested key value. Given a data structure that looks like this:
$data = { Elements => {
AlphaKey => {
Name => 'Foo',
Priority => 2,
OtherVal => 'randomthings'
},
BetaKey => {
Name => 'Bar',
Priority => 1,
OtherVal => 'morerandomthings'
},
}};
I want to process them in a sorted order based on the priority value. I'm trying to just turn the hashref into an arrayref, so that it winds up looking like:
$sorted = [
{
Name => 'Bar',
Priority => 1
OtherVal => 'morerandomthings'
},
{
Name => 'Foo',
Priority => 2,
OtherVal => 'randomthings'
},
];
It's easy enough to get a sorted list of priorities:
my @pri = sort { $a <=> $b } map { $data->{Elements}{$_}->{priority} }
+ keys %{$data->{Elements}};
I'm lost on how to build an arrayref-based structure from there. I'm not even sure i'm going down the right path now that I'm typing it out.
Thoughts?
