如何訪問SimpleXMLElement中的@attributes數據？

嘿傢伙我已經讀過關於stackoverflow buw上的同一主題的其他問題，我不知何故無法在我的場景中完成它。如何訪問SimpleXMLElement中的@attributes數據？

我想從xml文件中獲取一些特定的數據。

PHP代碼

$url = 'http://amdata.adlibsoft.com/wwwopac.ashx? 
database=AMcollect&search=priref=397*&xmltype=grouped'; 

$xml = file_get_contents($url); 
$xml = new SimpleXMLElement($xml);

做

print_r ($xml);

將返回

    (
     [record] => SimpleXMLElement Object 
      (
       [@attributes] => Array

      ) 

    ) 

)

現在讓我們說，我想我試過priref下面的事情

echo($xml->record->priref); 
echo $xml->record['priref'];

雙方沒有透露結果（顯示沒有錯誤，沒有什麼）

然後我試圖

echo $xml->record->attributes()->priref;

，並獲得「節點不再存在」

任何想法是什麼問題呢？

提前致謝！

這將讓你的屬性數組：

echo $xml->recordList->record[0]->attributes();

製作使用foreach和訪問它像key-value對顯示所需的值。

<?php 
$url = 'http://amdata.adlibsoft.com/wwwopac.ashx? 
database=AMcollect&search=priref=397*&xmltype=grouped'; 

$xml = file_get_contents($url); 
$xml = simplexml_load_string($xml); 
echo "<pre>"; 
foreach ($xml->recordList->record->attributes() as $k=>$a) 
{ 
    if($k=='priref') { echo $a; break;} 
}

OUTPUT :
