我是php和DOM新手，非常感谢您在这段代码中提供的帮助。这就是我目前所拥有的

试试这个：

<?php

$rss    = simplexml_load_file('http://www.example.com/feeds/events.xml');
$html   = "";
$dom    = new DOMDocument(); // the HTML parser used for descriptions' HTML

 foreach ($rss->channel->item as $item) {
     $title         = $item->title;
     $link          = $item->link;
     $description   = $item->description;

     foreach ($description as $desc)
    {
        $dom->loadHTML($desc);
        $html = simplexml_import_dom($dom)->body;
        // ?????
    }        

     $html .= "Title : $title <br /> Link : $link <br /> Description : $description <br /> Date : <br /> Location : <hr>";
}    
echo $html;

?>

或

使用
simplexml
，
DOMDocument
和
XPath

$document = new DOMDocument();
$document->load($xmlfile);

// this will also output doctype and comments at top level
foreach($document->childNodes as $node)
    $result .= $document->saveXML($node)."\n";

echo $result;
}

你好谢谢你的回复。我不知道这段代码将如何实现最终结果。这里的代码不考虑嵌套的div标签，这是这里的主要问题。你介意分享一下你的逻辑吗？那就行了！非常感谢你。
$xmlfile='http://www.example.com/feeds/events.xml';
    $xml = simplexml_load_file($xmlfile) or die("Error: Cannot create object");
    foreach($xml->children() as $item)
    {
     $title         = $item->title;
     $link          = $item->link;
     $description   = $item->description;
     $description   = $item->description;

             foreach ($description as $desc)
             {
              $title1         = $desc->title;
              $link 1         = $desc->link;
              $description1   = $desc->description;
             }   

    }

$document = new DOMDocument();
$document->load($xmlfile);

// this will also output doctype and comments at top level
foreach($document->childNodes as $node)
    $result .= $document->saveXML($node)."\n";

echo $result;
}

$rss    = simplexml_load_file('http://www.example.com/feeds/events.xml');

foreach($rss->channel->item as $item){

    print 'Title: ' . $item->title . PHP_EOL;
    print 'Link: ' . $item->link . PHP_EOL;

    $dom = new DOMDocument();
    $dom->loadHTML($item->description);

    $xpath = new DOMXpath($dom);

    $description = $xpath->query("//div[contains(@class, 'field-name-body')]");
    print 'Description: ' . $description->item(0)->nodeValue . PHP_EOL;

    $date = $xpath->query("//div[contains(@class, 'field-name-field-date')]");
    print 'Date: ' . $date->item(0)->nodeValue . PHP_EOL;

    $location = $xpath->query("//div[contains(@class, 'field-name-field-location')]/div/div");
    print 'Location: ' . $location->item(0)->nodeValue . PHP_EOL;   
}
