Parsing a List result - Ruby


#1

Hi Folks,

I need to parse a result that comes in this format :

=========================
ec2.describe_instances #=>
[{:aws_image_id => “ami-e444444d”,
:aws_reason => “”,
:aws_state_code => “16”,
:aws_owner => “000000000888”,
:aws_instance_id => “i-123f1234”,
:aws_reservation_id => “r-aabbccdd”,
:aws_state => “running”,
:dns_name =>
domU-12-34-67-89-01-C9.usma2.compute.amazonaws.com”,
:ssh_key_name => “staging”,
:aws_groups => [“default”],
:private_dns_name =>
domU-12-34-67-89-01-C9.usma2.compute.amazonaws.com”,
:aws_instance_type => “m1.small”,
:aws_launch_time => “2008-1-1T00:00:00.000Z”},
:aws_availability_zone => “us-east-1b”,
:aws_kernel_id => “aki-ba3adfd3”,
:aws_ramdisk_id => “ari-badbad00”,
…, {…}]

When I invoke the method,

puts @ec2.describe_instances

the results comes like this :

aws_image_idami-e444444daws_reasonaws_state_codeaws_owner000000000888aws_instance_id
i-123f1234aws_reservation_idr-aabbccddaws_staterunningdns_name
domU-12-34-67-89-01-C9.usma2.compute.amazonaws.comssh_key_namestagingaws_groups

Question :

Is there a way of accessing a specific key, for example : aws_status ?
If so, how do I do that ?

Thank you so much.

Regards.
