        I think this is not a exact output what i am expecting. 

        #!/usr/bin/perl --
use strict;
use warnings;
use HTML::TreeBuilder::XPath;

my $month;
my $date;
my $value;
my $tree= HTML::TreeBuilder::XPath->new_from_content(<<'HTML');
<body>
<div class="Row Jun-2015">
      <div class="Cell month-year ">
           Jun-2015
      </div>
      <div class="Cell Release Date ">
           2015-07-30
      </div>
      <div class="Cell National Mortgage Contract Rate ">
           3.850
      </div>

<div class="Row Jul-2015">
      <div class="Cell month-year ">
           Jun-2015                    </div>
