在过去的几天里，我一直在努力弄清楚为什么我的代码在本地运行良好，但在部署到生产服务器上时失败了。
我的本地测试环境是10.7.2 Lion iMac上的最新MAMP。
基本上，我需要从Artistdata.com获取某些XML RSS数据，以便将其插入到我正在开发的一个简单的PHP驱动的非CMS网站中
<!DOCTYPE html>
<html>
<head>
<title>RSS FEED Parser</title>
</head>
<body>
<?php
ini_set('display_errors',1);
ini_set('display_startup_errors',1);
error_reporting(-1);
# RSS Feed parser #
function getFeed($feed_url) {
$content = file_get_contents($feed_url);
$x = new SimpleXmlElement($content);
foreach ($x->show as $showEntry) {
echo '<div>';# date
$newDate = new DateTime($showEntry->date);
echo date_format($newDate, 'l, F j, Y');
echo '</div>';# /date
# further data fetching, totally unrelated
# to the problem that I'm experiencing
}
}
?>
<!-- START FEED PARSING -->
<div id="feed-data">
<?php getFeed('http://feeds.artistdata.com/xml.shows/artist/AR-30CA266E4BEDD78F/xml/future'); ?>
</div>
<!-- END FEED PARSING -->
</body>
</html>
我相信有更多的人有类似的问题，但我还没有找到一个可行的解决方案。
如果你有什么建议，我将不胜感激。

问题解决了，我使用了错误的提要，正确的是http://artistdata.sonicbids.com/john-latini/shows/xml/future
XML看起来不像RSS。它是由http://feeds.artistdata.com/_css/shows.xsd.
错误消息都表示您得到的是HTML（2.0）页面，而不是XML。我无法重现，我使用file_get_contents（）获取XML。
尝试输出HTML页面，也许它包含更多信息。
echo file_get_contents('http://feeds.artistdata.com/xml.shows/artist/AR-30CA266E4BEDD78F/xml/future');
