我不确定我的问题标题是否正确，但我尝试阅读一些RSS Feed（播客源）并使用相同的PHP代码，无法解析某些RSS源，并且其他人都被解析了。我不知道为什么，我也不知道如何找到错误。
我使用simplexml_load_file - 下面的代码：
<?php
//$xml = simplexml_load_file("http://hipsters.tech/feed/podcast/"); # it works
$xml = simplexml_load_file("https://jovemnerd.com.br/feed-nerdcast/"); # it doesn't works
# <channel> data
echo $xml->channel->title . "<br>\n";
echo $xml->channel->link . "<br>\n";
echo $xml->channel->language . "<br>\n";
echo $xml->channel->description . "<br>\n";
echo $xml->channel->image->url . "<br>\n";
$otherNode = $xml->channel->children('http://www.itunes.com/dtds/podcast-1.0.dtd');
echo $otherNode->author . "<br>\n";
echo "<br>#########################<br><br>\n";
# <item> data
for ($i = 0; $i < count($xml->channel->item); $i++ ) {
echo $xml->channel->item[$i]->title . "<br>\n";
echo $xml->channel->item[$i]->link . "<br>\n";
echo $xml->channel->item[$i]->pubDate . "<br>\n";
echo $xml->channel->item[$i]->description . "<br>\n";
echo "<br>#########################<br><br>\n";
}
?>
在我的代码中，您可以看到有2个链接，评论的链接有效，另一个无效。
我已经在堆栈和其他网站/论坛上看过其他帖子，但我真的不知道如何用一个代码解析任何RSS提要，没有头痛。
拜托，我需要一些帮助。谢谢。
