Answer 1

您仅获得该rss元素的第一个子元素，即channel的唯一子元素rss。这告诉它只循环一次。您需要指定您希望其子元素channel是多个item元素。

请尝试以下方法：

$xml = simplexml_load_file('data.xml') or die('Failed to create an object');

  foreach($xml->channel->children() as $xml_node) {          

    echo $xml_node->title . ", ";     

    echo $xml_node->description . ", ";     

}

item通过此更改，您可以访问:title和的直接子元素description。
