GuiPerl:

If you use Dumper to print out the data structure, you can look at the structure to see what to do. For example:

$VAR1 = (                # top level look at next item to see if array
+ or hash
   FOO=>{                # Key: top level is hash.  { means next is ha
+sh too
      BAR=>{             # another hash
         BAZ=>[          # square bracket starts an array
            { BIM=>1 },  # slot 0 contains a hash
            { BIM=>5 },  # slot 1 also contains a hash
            'GEORGE',    # slot 2 holds a string
            [3,6,9]      # slot 3 holds an array
         },
      },
   },
   FOE=>[                # FOE is key for an array
          ['a','b','c'], # slot 0 holds another array
          {FUM=>'FIE'},  # slot 1 holds a hash
   ],
);

say $H{FOO}{BAR}{BAZ}[0]{BIM};  # should show 1
say $H{FOO}{BAR}{BAZ}[2];       # should show GEORGE
say $H{FOO}{BAR}{BAZ}[3][1];    # should show 6
say $H{FOE}[0][2];              # should show c
say $H{FOE}[1]{FUM};            # should show FIE

So look at your Dumper output, and look at the characters used to separate the levels. You'll want to use the same characters to get to the data you want. Does that help clear things up?
