我有以下代码片段:
function getFeed($feed_url) {
$content = file_get_contents($feed_url);
$x = new SimpleXmlElement($content);
echo "<ul>";
foreach($x->channel->item as $entry) {
echo "<li><a href='$entry->link' title='$entry->title'>" . $entry->title . "</a></li>";
echo "<li>$entry->content</li>";
echo "</ul>";
}
它可以正常工作,但$entry->content
除外
这部分没有被记录下来。在实际的提要中,标签被列为<content:encoded>
,但我无法将其作为提要。有什么建议吗?

在<content:encoded>
中,content
是namespace,encoded
是标记名。
您必须使用SimpleXMLElement::children
。查看下面的输出
var_dump($entry->children("content", true));

我建议您使用以下代码:
function getFeed($feed_url) {
$feeds = file_get_contents($feed_url);
$feeds = str_replace("<content:encoded>","<contentEncoded>",$feeds);
$feeds = str_replace("</content:encoded>","</contentEncoded>",$feeds);
$rss = simplexml_load_string($feeds);
echo "<ul>";
foreach($x->channel->item as $entry) {
echo "<li><a href='$entry->link' title='$entry->title'>" . $entry->title . "</a></li>";
echo "<li>$entry->contentEncoded</li>";
echo "</ul>";
}
希望这对你有用。

……PHP示例
<?php
// --------------------------------------------------------------------
$feed_url = 'http://www.tagesschau.de/xml/rss2';
$xml_data = simplexml_load_file($feed_url);
// --------------------------------------------------------------------
$i=0;
foreach($xml_data->channel->item as $ritem) {
// --------------------------------------
$e_title = (string)$ritem->title;
$e_link = (string)$ritem->link;
$e_pubDate = (string)$ritem->pubDate;
$e_description = (string)$ritem->description;
$e_guid = (string)$ritem->guid;
$e_content = $ritem->children("content", true);
$e_encoded = (string)$e_content->encoded;
$n = ($i+1);
// --------------------------------------
print '<p> ---------- '. $n .' ---------- </p>'."\n";
print "\n";
print '<div class="entry" style="margin:0 auto; padding:4px; text-align:left;">'."\n";
print '<p> Title: '. $e_title .'</p>'."\n";
print '<p> Link: '. $e_link .'</p>'."\n";
print '<p> Date: '. $e_pubDate .'</p>'."\n";
print '<p> Desc: '. $e_description .'</p>'."\n";
print '<p> Guid: '. $e_guid .'</p>'."\n";
print '<p> Content: </p>'."\n";
print '<p style="background:#DEDEDE">'. $e_encoded .'</p>'."\n";
print '</div>'."\n";
// --------------------------------------
print '<br />'."\n";
print '<br />'."\n";
$i++;
}
// --------------------------------------------------------------------
?>
如果您希望在浏览器中查看内容HTML源代码,请使用例如:
print '<pre style="background:#DEDEDE">'. htmlentities($e_encoded) .'</pre>'."\n";
