</Pages>

PHP：

$xml = simplexml_load_file($dir) 
       or die("Error: Cannot create object");
//$fileList = array();

foreach($xml->children() as $Pages){
    foreach($Pages->children() as $Page => $page){
    $fileLink = $page['ThumbnailPath'];
    echo $fileLink;
    }
}

我将得到的是来自节点“页面”的ThumbnailPath，我循环浏览页面和页面，但事实证明什么都没有，如何解决这个问题？感谢

Answer 1

很容易修复

$xml = simplexml_load_file("test.xml")
       or die("Error: Cannot create object");
//$fileList = array();


foreach($xml->children() as $Pages){
    print_r($Pages['ThumbnailPath']);
}

Answer 2

您不必遍历“Pages”，因为它已经是xml根元素。所以你可以省略第二个循环：

 $xml = simplexml_load_string($string) or die("Error: Cannot create object");
 //$fileList = array();

foreach($xml->children() as $Page){
    $fileLink = $Page['ThumbnailPath'];
    echo $fileLink;
}

Answer 3

试试这个：

foreach($xml->children() as $Pages){
    echo $Pages['ThumbnailPath'][0].'<br>';
}

无法使用PHP获取XML属性值
