Subject: Re: need to help to get data from bellow syntax

Something like this, maybe:

    bellow_syntax = [{:name=>"value1"}, {:name=>"Value2"}]
    puts bellow_syntax.map{ |hash|
      name = hash[:name]
      name =~ /^V(alu)e(2)$/ ? "v#$1#$2" : name
    }

... but that's mean.

[...] means an array, so you can use .each to iterate over its members.
{...} means a hash, so you can use foo[bar] to access its members
:foo means a symbol, which is just a ruby datatype

    ary = [{:name=>"value1"}, {:name=>"value2"}]
    ary.each do |hsh|
      # hsh == {:name=>"valueX"}
      # hsh[:name] == "valueX"
      puts hsh[:name]
    end
