嗨我正在尝试获取具有特定内容或值的所有节点的计数。在这种情况下,我有一个XML像这样:在php和xml中获取包含特定值的xml节点的数量
<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>
我需要找到与4的值的所有hotelRating并计算有多少在我的XML列表。我不知道如何用php做到这一点。如果有人能帮助我,我会非常感激!
顺便说一下,我已经连接了如下的XML文件,并能够获取数据和发送数据。
$post_string= 'type=xml&cid=222&minorRev=14&apiKey=222&locale='.$userLocale.'¤cyCode='.$userCurr.'&customerIpAddress='.$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');
}
非常感谢您的帮助!
