Subject: Re: Add value inside 'Nested Mappings String'

In your example, there's only one element in the Array, and 4 elements
in the inner Hash.

Step-by-step...

1) Returns an Array.

a["System"]["H&S"]["children"]

 #=> [{"name"=>"Training and Culture", "type"=>"Objective",
"subtype"=>"None", "components"=>"None"}]

2)  Returns the first element of the Array. It's the Hash you're
trying to manipulate.

a["System"]["H&S"]["children"][0]

# => {"name"=>"Training and Culture", "type"=>"Objective",
"subtype"=>"None", "components"=>"None"}

3) Now that you have the Hash, you can access its pairs (key,value).

a["System"]["H&S"]["children"][0]["type"]
#=> "Programme"

4) Or, set it...

a["System"]["H&S"]["children"][0]["type"] = "Objective"
