RSS feed在PHP中返回纯文本而不是HTML?


I am trying to extract content from this feed. This is the code I am using:

$rss  = new DOMDocument();

foreach ($rss->getElementsByTagName('entry') as $node) {
   $description = $node->getElementsByTagName('content')->item(0)->nodeValue;
   echo $description;

This however, instead of echoing HTML echoes plain text. Here is the strucutre of feed.

<link rel=".." type="..." href="...." />
...... More tags ......
<content type="xhtml" xml:lang="en-US"  xml:base="http://www.abeautifulmess.com/">
  <div xmlns="http://www.w3.org/1999/xhtml"> HTML is all here.

It has not happened with any other feed. Is it because of type of content or something else?

    Using DOMDocument::saveHTML will preserve the html formatting of the node. This will give you what you want:

    $feed_url = 'http://feeds.feedburner.com/a_beautiful_mess?format=xml';
    $rss  = new DOMDocument();
    foreach ($rss->getElementsByTagName('entry') as $node) {
       $description = $node->getElementsByTagName('content')->item(0);
       echo $rss->saveHTML($description);
