Subject: Adding contents on yaml file without overwriting actual contents

Hi,

By running the following codes:
---------------------------------------------------------------------------
convert_yaml = YAML::load_file('nizam.yaml')
    pp
convert_yaml["System"]["Environmental"]["children"][2]["children"]
    convert_yaml["System"] = { "children" =>
         [{"name"=>"nizam",
           "type"=>"Objective",
           "subtype"=>"None",
           "components"=>
            [{"type"=>"ContentBox",
              "title"=>"Audit",
              "args"=>{:content=>"None\n"}},
             {"type"=>"ChildListingComponent",
              "title"=>"Current Targets for the Audit Objective:"}]}]}
    File.open("nizam_out.yaml", "w"){|f| YAML.dump(convert_yaml, f)}

My yaml output turns out to be like this:
--------------------------------------------------------------------------
System:
  children:
  - name: nizam
    type: Objective
    subtype: None
    components:
    - type: ContentBox
      title: Audit
      args:
        :content: |
          None

    - type: ChildListingComponent
      title: "Current Targets for the Audit Objective:"

The actual yaml file before being converted is:
---------------------------------------------------------------------------
System:
  H&S:
    name: "Health & Safety"
    components:
    - FlashWheel
    children:
    - name: "Training and Culture"
      type: Programme
      subtype: None
      components:
      - type: ContentBox
        title: "Training and Culture"
        args:
          :content: |
            None
      - type: ChildListingComponent
        title: "Training and Culture Programme Objectives"
    #Children named nizam should be added here
      children:
      - name: "Team"
        type: Objective
        subtype: None
        components:
        - type: ContentBox
          title: "Team"
          args:
            :content: |
              None
        - type: ChildListingComponent
          title: "Current Targets for the Team Objective:"

My question is how do i add children named 'nizam' under "Health &
Safety" without jeopardizing other contents (i.e "Training and Culture"
and further contents of H&S). I think YAML.dump in not the correct way
to do it. Thanks in advance.

Nizam
