这样的xml我该怎么读取啊

simplexml_load_string 得到数组循环就得了

用这个方法PHP xml 转数组

用读出来的下标对应就行吧

谁给你的 xml 骂一顿先

这种只能自己处理了吧

大力出奇迹，正则YYDS

$xml = '<dict>
    <key>AvailableDeviceCapacity</key>
    <real>115.94891264</real>
    <key>AwaitingConfiguration</key>
    <false/>
    <key>BatteryLevel</key>
    <real>0.79000000000000004</real>
</dict>';

$data = simplexml_load_string($xml);
foreach ($data as $k => $v)
{
    var_dump($k, (array) $v);
    echo "<hr>";
}

$xml = '<dict>
    <key>AvailableDeviceCapacity</key>
    <real>115.94891264</real>
    <key>AwaitingConfiguration</key>
    <false/>
    <key>BatteryLevel</key>
    <real>0.79000000000000004</real>
</dict>';

$data = simplexml_load_string($xml);
foreach($data->children() as $child){
    echo $child->getName() . '...' . $child . PHP_EOL;
}

看了这位老哥的推荐，补充了标签名方便判断重新格式化 @zmxyzmxy1234

解析函数

function fuck_process_xml($xml)
{
    $dom = new \DOMDocument();
    $dom->loadXML($xml);
    $element = $dom->getElementsByTagName('dict')[0];
    $children = $element->childNodes;
    $map = [];
    $processingKey = null;
    foreach ($children as $child) {
        if (empty($child->tagName)) {
            continue;
        }
        switch ($child->tagName) {
            case 'key':
                $processingKey = $child->nodeValue;
                break;
            case 'false':
                $map[$processingKey] = false;
                break;
            case 'true':
                $map[$processingKey] = true;
                break;
            case 'real':
                $map[$processingKey] = $child->nodeValue;
                break;
            default:
                // 继续补全其他类型
                throw new \Exception('未能处理 : ' . print_r($child, true));
        }
    }
    return $map;
}

使用

$xml = '<dict>
    <key>AvailableDeviceCapacity</key>
    <real>115.94891264</real>
    <key>AwaitingConfiguration</key>
    <false/>
    <key>BatteryLevel</key>
    <real>0.79000000000000004</real>
</dict>';
echo json_encode(fuck_process_xml($xml), JSON_PRETTY_PRINT);

返回

{
    "AvailableDeviceCapacity": "115.94891264",
    "AwaitingConfiguration": false,
    "BatteryLevel": "0.79000000000000004"
}

file函数逐行读取。

叉哎母哎了
