Accessing values of json structure in perl

Question

I have a json structure that I\'m decoding that looks like this:

  person => {
    city => \"Chicago\",
    id => 123,
    name => \"Joe Smith\",         


        

Answer 1

Assuming your $listing is a person you have to dereference array and hash refs.

# as long as we are assuming $listing is a person
# this goes inside the foreach you posted in your
# question.

# this will print all cats' names
foreach my $cat ( @{ $listing->{pets}->{cats} } )
{
    # here $cat is a hash reference

    say $cat->{name}; # cat's name
}

and so on for other stuff.

To access them from the structure you can do:

say $listing->{pets}->{cats}->[0]->{name}; # this will print 'cat1'
