I have tried like this code to retrieve data from the xml. 我已经尝试过像这样的代码从xml检索数据。

Below I have attached the code used to retrieve data from the xml 下面我附上了用于从xml检索数据的代码 

$xml  = simplexml_load_string("myxml.xml");
foreach($xml as $hotel) { 
   echo "Hotel Name: ".$hotel->hotel['name']."<br>";
   echo "Hotel Category: ".$hotel->hotel['categoryName']."<br>";
   echo "Hotel Destination: ".$hotel->hotel['destinationName']."<br>";
   echo "Room Name: ".$hotel->hotel->rooms->room['name']."<br>";
   //echo "<br>"; 
}

But the result is 但是结果是 

 Hotel Name: Hotel Category: Hotel Destination: Room Name: Hotel Name: Armadams Hotel Category: 4 STARS Hotel Destination: Majorca Room Name: Double or Twin STANDARD

All room data are not getting and displaying, is there any other way to read data from xml? 所有会议室数据均未获取和显示，是否还有其他方法可以从xml读取数据？

$xml in your code probably refers to root element, that is <availabilityRS> . 您代码中的$xml可能引用根元素，即<availabilityRS> 。 You need to change your loop to get to <hotels> and <hotel>s. 您需要更改循环以转到<hotels>和<hotel>s. and their rooms. 和他们的房间。 Also you'll need to change simplexml_load_string to simplexml_load_file if you are reading XML data from a file: 另外，如果您正在从文件中读取XML数据，则还需要将simplexml_load_string更改为simplexml_load_file ： 

$xml = simplexml_load_file(__DIR__.'/myxml.xml');

foreach ($xml->hotels[0] as $hotel) {
    echo $hotel['name']."<br>";
    echo $hotel['categoryName']."<br>";
    echo $hotel['destinationName']."<br>";
    echo "rooms:<br>";
    foreach ($hotel->rooms[0] as $room) {
        echo $room['name']."<br>";
    }
}

sample code below can help: 下面的示例代码可以帮助您： 

<?php
$availabilityrs = simplexml_load_file('temp.xml');
$hotel = $availabilityrs->hotels->hotel;
$room_nodes = $hotel->rooms->room;
foreach ($room_nodes as $room) {
    echo "Hotel Name: ".$hotel['name']."\n";
    echo "Hotel Category: ".$hotel['categoryName']."\n";
    echo "Hotel Destination: ".$hotel['destinationName']."\n";
    echo "Room Name: ".$room['name']."\n";
}

please refer this manul : 请参阅此手册 ：

When multiple instances of an element exist as children of a single parent element, normal iteration techniques apply. 当一个元素的多个实例作为单个父元素的子代存在时，将应用常规迭代技术。

If hotel is mutiple, you should iterate it too. 如果hotel多，您也应该对其进行迭代。

Traversing XML elements the object-oriented way could be messy for some people. 以面向对象的方式遍历XML元素对于某些人来说可能是一团糟。 It's better have them converted to array elements and it then makes easier to iterate through them. 最好将它们转换为数组元素，然后更容易遍历它们。 Here is the code to convert the XML object to array and traversing through them: 这是将XML对象转换为数组并遍历它们的代码： 

$xml = simplexml_load_file('myxml.xml');
$xml = json_decode(json_encode($xml), true);
$hotel = $xml['hotels']['hotel'];

foreach($hotel['rooms'] as $rooms) {
    foreach($rooms as $room) {
        echo "<p>Hotel Name: {$hotel['@attributes']['name']}</p>";
        echo "<p>Hotel Category: {$hotel['@attributes']['categoryName']}</p>";
        echo "<p>Hotel Destination: {$hotel['@attributes']['destinationName']}</p>";
        echo "<p>Room Name: {$room['@attributes']['name']}</p>";
        echo "<br><br>";
    }
}

Hope it helps! 希望能帮助到你！
