Question

以下PHP已经工作了几年：

<?php
    $counter = 0;
    $rss = new SimpleXMLElement('http://groups.google.com/group/boy-scout-troop-845/feed/rss_v2_0_msgs.xml', null, true);
?>

现在产生的错误如下：

Warning: SimpleXMLElement::__construct() [simplexmlelement.--construct]: ... parser error : Opening and ending tag mismatch: meta line 1 and head in /home/content/t/r/o/troo9757/html/index.php on line 119

请注意，我已用“...”替换了链接，以便接受此操作。我查看了返回的XML，看起来很好。是不是有可能它太长了？这里有什么建议吗？

谢谢！

Google似乎已将其RSS源更改为将HTTP流量重定向到HTTPS。如果您查看您尝试获取的XML文件的响应，它实际上会返回带有重定向标记的HTML。

只需直接致电https即可解决此问题。

$rss = new SimpleXMLElement('https://groups.google.com/group/boy-scout-troop-845/feed/rss_v2_0_msgs.xml', null, true);

打开和结束标记不匹配：来自Google网上论坛的RSS Feed中的元线1和头部
