PHP解析所有.mp3链接的XML文件

Question

我正在尝试编写一个PHP脚本，解析https://feeds.transistor.fm/the-good-news-podcast上所有.mp3的XML文件，然后回显它们。我已经开始使用PHP的simplexml_load_file（）了。 mp3的位置如下：

<enclosure url="https://media.transistor.fm/025fe5da.mp3" length="3636030" type="audio/mpeg"/>

我如何定位所有机箱标签网址？这是我到目前为止，但它没有工作：

<?php
    $mysongs = simplexml_load_file('https://feeds.transistor.fm/the-good-news-podcast');
    foreach ($mysongs as $songinfo):
        $title=$songinfo->enclosure(url);
        echo $title;
    endforeach; 
?>

也试过这个，但没有运气：

<?php
$html= simplexml_load_file('https://feeds.transistor.fm/the-good-news-podcast');
$dom = new DOMDocument;
$dom->loadXML($html);
foreach ($dom->getElementsByTagName('enclosure') as $tag) {
        if(strpos($tag->getAttribute('url'),'.mp3')!==false)
        {
            echo $tag->getAttribute('url')."<br>";
        }

}
?>

Answer 1

刚刚想通了Get enclosure img url from rss feed：

<?php
$rss=simplexml_load_file('https://feeds.transistor.fm/the-good-news-podcast');
foreach ($rss->channel->item as $item) {
    if (isset($item->enclosure)) {
        echo $item->enclosure['url'].'<br>';
    }
}
?>

Answer 2

如果应用它，您可以尝试简单的方法。

$html= simplexml_load_file('https://feeds.transistor.fm/the-good-news-podcast');
preg_match_all("/h.*mp3/", $html, $mp3s);
foreach ($mp3s as $mp3){
echo $mp3.'<br>';
}

这将输出

array(1
0   =>  array(9
0   =>  https://media.transistor.fm/0cf8f8b1.mp3
1   =>  https://media.transistor.fm/f45a0d7d.mp3
2   =>  https://media.transistor.fm/2ba746c9.mp3
3   =>  https://media.transistor.fm/025fe5da.mp3
4   =>  https://media.transistor.fm/58cf9a08.mp3
5   =>  https://media.transistor.fm/65a6df2b.mp3
