您好,我試圖訪問包含屬性=某個值的元素。我正在使用Expedia API,但無法使其工作。這裏是我如何連接到XML文件:在xml和php中獲取匹配某個值的元素的屬性

$ch = curl_init(); 
$fp = fopen('room.xml','w'); 
curl_setopt($ch, CURLOPT_URL, "http://api.ean.com/ean-services/rs/hotel/v3/info?cid=55505&minorRev=13&apiKey=4sr8d8bsn75tpcuja6ypx5g3&locale=en_US&currencyCode=USD&customerIpAddress=10.184.2.9&customerUserAgent=Mozilla/5.0+(Windows+NT+6.1)+AppleWebKit/535.11+(KHTML,+like+Gecko)+Chrome/17.0.963.79+Safari/535.11&customerSessionId=&xml=<HotelInformationRequest><hotelId>".$hid."</hotelId><options>0</options></HotelInformationRequest>"); 
curl_setopt($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('room.xml'); 

那麼這裏就是XML響應的例子:

<ns2:HotelInformationResponse xmlns:ns2="http://v3.hotel.wsapi.ean.com/" hotelId="121196"> 
    <customerSessionId>0ABAA871-3187-D691-3682-CC27421918AC</customerSessionId> 
    <HotelSummary order="0">...</HotelSummary> 
    <HotelDetails>...</HotelDetails> 
    <Suppliers size="2">...</Suppliers> 
    <RoomTypes size="9"> 
    <RoomType roomCode="17918" roomTypeId="136767"> 
    <description>Deluxe Sunset View</description> 
    <descriptionLong> 
    One king or two double beds. 38.5 meters (414 square feet). Floors 1–9. Complimentary wireless Internet access. CD/DVD player. MP3 docking station. Complimentary newspapers. Minibar. Coffeemaker. Bathroom with shower only. Aveda toiletries. Bathrobes. Bathroom scale. Laptop-compatible safe. Turndown service. 
    </descriptionLong> 
    </RoomType> 
    </RoomTypes> 

而且最後這裏是我正在試圖訪問它:

<?php $dataroom = $data->RoomTypes->RoomType['@roomCode="17918"']->description; var_dump($dataroom); ?> 

正如你所看到的,我試圖訪問roomCode = 17918的描述,但它不起作用!我曾嘗試使用回聲和打印,沒有任何作品。 var_dump返回NULL的值。我不知道我做錯了什麼。我可以得到我想要的任何其他元素,但不是我需要它匹配的地方。

也許你應該追加' - > data'到'description'的末尾? – 2012-04-07 21:35:56

不知道:(沒有工作。 – liveandream 2012-04-07 21:40:11

試試這個:

$dataroom = get_object_vars($data->RoomTypes->RoomType); 
if($dataroom['@attributes']['roomCode'] == 17918) echo $dataroom['description']; 

當然,你將不得不相應地增加額外的循環,但這應該只是罰款,我只用一個在線代碼執行工具來測試它,似乎工作。

您嘗試的方法不是特別正確。您正嘗試以數組的形式訪問對象。我將該對象轉換爲數組,然後以數組的形式訪問它。

我想通了......謝謝大家的幫助......絕對幫助我朝着正確的方向發展!下面是我如何解決它:

foreach($data->RoomTypes->RoomType AS $match){ 
    if($match['roomCode']== "$roomCode"){ 
     echo $match->descriptionLong; 
    }}
