      [PRODUCT] => Array

        [1] => SimpleXMLElement Object 
         (

这是我在print_r($xml);我怎么循环[0]，[1]和访问其元素。我需要每个产品的[PRODUCTS_NAME]。任何帮助，将不胜感激。

Answer 1

$xml = <<<XML 

<EXPORT-RECORDS> 
     <PRODUCT> 
      <PRODUCTS_NAME>Panasonic Super Heavy Duty Battery AA - 4 Pack</PRODUCTS_NAME> 
      <PRODUCTS_DESCRIPTION>Batteries keep going and going and going until they don\'t. And there\'s nothing more disappointing than </PRODUCTS_DESCRIPTION> 
     </PRODUCT> 
     <PRODUCT> 
      <PRODUCTS_NAME>Panasonic Super Heavy Duty Battery AA - 4 Pack</PRODUCTS_NAME> 
      <PRODUCTS_DESCRIPTION>Batteries keep going and going and going until they don\'t. And there\'s nothing more disappointing than</PRODUCTS_DESCRIPTION> 
     </PRODUCT> 
</EXPORT-RECORDS> 
XML; 

$xml = simplexml_load_string($xml); 

foreach($xml->PRODUCT as $PRODUCT){ 
    echo $PRODUCT->PRODUCTS_NAME; 
}

Answer 2

foreach($SimpleXMLElement['EXPORT-RECORDS']['PRODUCT'] as $Key => $Dataset){ 
    /* Do whatever you want with $Key and $Dataset */ 
} 

该循环应该这样做。作为一个例子，

echo $Dataset['PRODUCTS_NAME']; 

将放置在Loop的主体中，回显所有产品名称。
