import "../import/junos.xsl";



match / {

    <op-script-results> {

        <output method= "text"> {

        var $ip_address = "192.168.1.1";



          expr "BEFORE " _ $ip_address _ "\n";



          var $field = jcs:split('\\.', $ip_address);



          expr "AFTER ";



            for-each ($field) {



               call dec_to_hex($value = .);

            }

        }

    }

}



template dec_to_hex ($value) {



    if ($value >= 16) {

        call dec_to_hex($value = floor($value div 16));

    }

    var $hex_digits = "0123456789ABCDEF";

    expr substring($hex_digits,($value mod 16) + 1, 1);
