Question

我有这个xml文件（见下文），我想用php解析输出Filename和RomUrl

<?xml version="1.0" encoding="UTF-8"?>
<OTA xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="ota.xsd">
    <Stable>
        <cheeseburger>
            <Filename>crDroidAndroid-8.1-20180128-cheeseburger-v4.0-BETA5</Filename>
            <RomUrl
                id="rom"
                title="Downloads"
                description="Download latest builds">dl url here for cheeseburger</RomUrl>
        </cheeseburger>

        <dumpling>
            <Filename>crDroidAndroid-8.1-20180127-dumpling-v4.0-BETA</Filename>
            <RomUrl
                id="rom"
                title="Downloads"
                description="Download latest build">dl url here for dumpling</RomUrl>
        </dumpling>
     </Stable>
</OTA>

我希望能够像这样输出：

cheeseburger
crDroidAndroid-8.1-20180128-cheeseburger-v4.0-BETA5
dl url here for cheeseburger

dumpling
crDroidAndroid-8.1-20180127-dumpling-v4.0-BETA
dl url here for dumpling

现在我被困在循环每个元素这是我到目前为止的代码

<?php
// Devices.xml reader 

// check if file exists and read it
if (file_exists('devices.xml')) {
    $xml = simplexml_load_file('devices.xml');

    //echo $xml->Stable->dumpling->Filename;
    echo "<br>";
    foreach($xml->Stable as $device) {
        echo '<h2>' . $device->Filename . '</h2>';
    }
    echo "<br>";
    echo "<br>";
    //var_dump($xml);
} else {
    exit('Failed to open devices.xml.');
}
?>

现在我确信可能有更好的选择，但我不熟悉php中的XML，所以任何帮助都非常感谢

谢谢

$device的类型为SimpleXMLElement，您可以使用foreach进行循环。

然后，您可以访问$key以获取“cheeseburger”和$item（也是SimpleXMLElement类型）以获取“Filename”等属性。

if (file_exists('devices.xml')) {
    $xml = simplexml_load_file('devices.xml');
    foreach($xml->Stable as $device) {
        foreach ($device as $key => $item) {
            echo $key . "<br>";
            echo $item->Filename . "<br>";
            echo $item->RomUrl . "<br>";
            echo "<br>";
        }
    }
} else {
    exit('Failed to open devices.xml.');
}

这将导致：

cheeseburger
crDroidAndroid-8.1-20180128-cheeseburger-v4.0-BETA5
dl url here for cheeseburger

dumpling
crDroidAndroid-8.1-20180127-dumpling-v4.0-BETA
dl url here for dumpling
