simplexml閱讀enclousure html標記

Question

如何使用simplexml讀取iTunes RSS中的機箱url標記？

FEED：

<?xml version="1.0" encoding="UTF-8"?> 
<rss xmlns:itunes="http://www.itunes.com/dtds/podcast-1.0.dtd" version="2.0"> 

<channel> 
<item> 
    <itunes:subtitle> subtitle </itunes:subtitle> 
    <enclosure url="http://www.myWe/mySound.mp3" length="624557" type="audio/mp3"/> 
</item> 
</channel> 
</rss> 

PHP：

foreach ($feed->channel->item as $item) { 
    $iTunes_item = $item->children('http://www.itunes.com/dtds/podcast-1.0.dtd'); 

    $item_subtitle = $item->subtitle->attributes(); 
    $item_url = $iTunes_item->enclosure->attributes('url'); // enclosure url 

    echo $item_subtitle; 
    echo $item_url; 
} 

Answer 1

訪問URL使用;

rss->channel->item->enclosure->attributes()->url 

試試這個獲取小標題;

$namespaces = $item->getNameSpaces(true); 
$nodes = $item->children($namespaces['itunes']); 
echo $nodes->subtitle;
