在php和xml中獲取包含特定值的xml節點的數量

嗨我正在嘗試獲取具有特定內容或值的所有節點的計數。在這種情況下，我有一個XML像這樣：在php和xml中獲取包含特定值的xml節點的數量

<hotel> 
<city>Cancun</city> 
<postalCode>77500</postalCode> 
<countryCode>MX</countryCode> 
<airportCode>CUN</airportCode> 
<supplierType>E</supplierType> 
<propertyCategory>1</propertyCategory> 
<hotelRating>4.0</hotelRating> 
<confidenceRating>52</confidenceRating> 
</hotel>

我需要找到與4的值的所有hotelRating並計算有多少在我的XML列表。我不知道如何用php做到這一點。如果有人能幫助我，我會非常感激！

順便說一下，我已經連接瞭如下的XML文件，並能夠獲取數據和發送數據。

$post_string= 'type=xml&cid=222&minorRev=14&apiKey=222&locale='.$userLocale.'&currencyCode='.$userCurr.'&customerIpAddress='.$userIp.'&customerUserAgent='.$userAgent.'&xml=<HotelListRequest><destinationId>'.$destinationId.'</destinationId><arrivalDate>'.$arriving.'</arrivalDate><departureDate>'.$departing.'</departureDate><RoomGroup>'.$xmlQuery.'</RoomGroup><supplierCacheTolerance>MED_ENHANCED</supplierCacheTolerance></HotelListRequest> '; 
//Relative path to the file with $_POST parsing 
$path = "http://api.ean.com/ean-services/rs/hotel/v3/list"; 
$ch = curl_init($path); 
$fp = fopen('xml/data.xml','w'); 
//Send the data to the file 
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_string); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Accept: application/xml')); 
curl_setopt($ch, CURLOPT_HEADER, 0); 
curl_setopt($ch, CURLOPT_FILE, $fp); 
$val = curl_exec($ch); 
curl_close($ch);//Close curl session 
fclose($fp); //Close file overwrite 
$data = simplexml_load_file('xml/data.xml'); 
}

非常感謝您的幫助！

foreach ($data->hotel as $hotel) 
{ 
    if ($hotel->hotelRating == '4.0') 
    { 
     // hotel with 4.0 rating found 
    } 
}

$count = $data->xpath("count(\"//hotel[hotelRating= '4.0']\")");

會給你的酒店，其中hotelrating = 4.0的計數。
