Youtube API 从 XML 获取视频时长 [英] Youtube API get video duration from the XML

问题描述

考虑 Youtube API XML 文件，例如 http://gdata.youtube.com/feeds/api/videos/$id一个特定的 XML 数据文件是 http://gdata.youtube.com/feeds/api/videos/GI6CfKcMhjY以下函数根据 XML url 获取视频的标题:

Consider Youtube API XML files like http://gdata.youtube.com/feeds/api/videos/$id One particular XML data file is http://gdata.youtube.com/feeds/api/videos/GI6CfKcMhjY The following function gets the title of the video according to the XML url:

function ytTitle($ytid,$ytURLConstant){
    $url = $ytURLConstant.$ytid;
    $doc = new DOMDocument;
    $doc->load($url);
    echo $title = $doc->getElementsByTagName("title")->item(0)->nodeValue;
}

如我所见，XML 文件中有视频时长:

As I see there is video duration in the XML file:

<media:title type='plain'>Jack Sparrow (feat. Michael Bolton)</media:title><yt:duration seconds='197'/>

由于我是 XML 新手，任何有关获取视频时长的帮助将不胜感激.

As I am an XML newbie any help concerning getting the video duration will be greatly appreciated.
