      @if($key == 'Name')
      <b></b> - 
      @endif
      @if($key == "RRPText")
      <b></b>
      @endif
      @endforeach
      @foreach($result['Domains']['Domain']['Prices'] as $key => $value)
      @if($key == "Registration")
      <b></b>
      @endif 
      @endforeach

My Controller Code

$sld = $request['sld'];
        $tld = $request['tld'];
        $response = file_get_contents('https://reseller.enom.com/interface.asp?command=check&sld='. $sld .'&tld='. $tld .'&uid=resellid&pw=resellpw&responsetype=xml&version=2&includeprice=1&includeproperties=1&includeeap=1');  
        $data = simplexml_load_string($response);
