【问题描述】：

     SimpleXMLElement Object
 (
        [@attributes] => Array
            (
                [projectTypeID] => 10
                [genContentID] => 000001
                [language] => en
                [title] => Travel to developing countries
                [subContent] => default
            )

        [versionInfo] => SimpleXMLElement Object
            (
                [@attributes] => Array
                    (
                        [reviewDate] => 2/20/2012
                        [reviewedBy] => Harvey Simon
                    )

            )
     ) 

如何获取@attributes 元素的值？

   [title] => Travel to developing countries

   [reviewDate] => 2/20/2012

这是我的代码

  <?php   $xml = simplexml_load_file('000001.xml','SimpleXMLElement', LIBXML_NOCDATA);


          echo "<pre>";
           print_r($xml);
          echo "</pre>";

             echo $xml->'@attributes'['title'];  // not working
        echo "<br/>";
       echo $xml->versionInfo->'@attributes'['reviewDate'];   // not working

   ?>

【参考方案1】：

试试下面的代码：

foreach($xml as $key => $value)
      foreach($value->attributes() as $attributeskey0 => $attributesvalue1)
              echo "________[$attributeskey0] = $attributesvalue1";
      

【参考方案2】：

使用 attributes() 方法：

$attrs = $xml->versionInfo->attributes();
echo $attrs['reviewDate'];
