XML：將幾個子節點的值保存到php數組中

如何檢索此xml的所有<ASIN>..</ASIN>值並將它們保存到php變量/數組中？XML：將幾個子節點的值保存到php數組中

我試過$result=$xml->xpath('//ASIN');但這給了我array(0) { }作爲瀏覽器輸出。謝謝你的幫助！我非常感激！

這是我的xml文件：

<?xml version="1.0" ?> 
     <ItemLookupResponse xmlns="http://webservices.amazon.com/AWSECommerceService/2011-08-01"> 
     <OperationRequest>

因爲命名空間的你不能夠直接執行XPath查詢。閱讀完整的詳細信息解決方案here

我仍然在這裏提供一點點代碼，可以幫助你。

$asins = simplexml_load_file('asin.xml'); 
if(count($asins)): 
    //alternate way other than registring NameSpace 
    //$asin = $asins->xpath("//*[local-name() = 'ASIN']"); 

    $asins->registerXPathNamespace('prefix', 'http://webservices.amazon.com/AWSECommerceService/2011-08-01'); 
    $asin = $asins->xpath("//prefix:ASIN"); 
    echo "<pre>";print_r($asin); 
endif;

現在你會看到數組off ASIN元素像下面

Array 
(
    [0] => SimpleXMLElement Object 
     (
      [0] => B007ZXLRVQ 
     ) 

    [1] => SimpleXMLElement Object 
     (
      [0] => B007Y6DS84 
     ) 

    [2] => SimpleXMLElement Object 
     (
      [0] => B0018K7EMI 
     ) 

    [3] => SimpleXMLElement Object 
     (
      [0] => B000QG7AJM 
     ) 

    [4] => SimpleXMLElement Object 
     (
      [0] => B001T9N51M 
     ) 

    [5] => SimpleXMLElement Object 
     (
      [0] => B001ET6CNU 
     ) 

)
