I need to extract the data elements in a data file containing curly brace neted data to produce a list of NAT pairs. For example, here is a dump from our Palo Alto FW: 

------------------
Sample input

         {
            {
                {
                Prod1_Core_10.2.6.1 {
                  to WAN;
                  from WAN;
                  source any;
                  destination 8.39.63.3;
                  service service-https;
                  to-interface any;
                  destination-translation {
                    translated-address 10.2.6.1;
                  }
                  description "Static NAT to Core 10.2.6.1";
                }
                Prod1_Core_10.2.6.2 {
                  to WAN;
                  from WAN;
                  source any;
                  destination 8.39.63.4;
                  service service-https;
                  to-interface any;
                  destination-translation {
                    translated-address 10.2.6.2;
                  }
                  description "Static NAT to Core 10.2.6.2";
                }
            }
         }

end sample input

Essentially, we want to extract these values:

    >>>>     Prod1_Core_10.2.6.2 {
                  to WAN;
                  from WAN;
                  source any;
    >>>>     destination 8.39.63.4; 
                  service service-https;
                  to-interface any;
                  destination-translation {
    >>>>     translated-address 10.2.6.2;  <<<<

From this data we need to produce a list of the nat pairs like:

queue = [
  {:corename => "Prod1_Core_10.2.6.1", :pubip => "8.39.63.3",  :privip
+ => "10.2.6.1"},
  {:corename => "Prod1_Core_10.2.6.2", :pubip => "8.39.63.4", :privip 
+=> "10.2.6.2"},
  ]

Is there a parser that will be able to map the data blocks in the nested data into single entities like a string?

any guidance is greatly appreciated :)
