获得总结果Youtube Api PHP

Question

嘿，现在我正在解析youtube的api

demo url:

http://gdata.youtube.com/feeds/api/videos/-/test?orderby=viewCount&start-index=1&max-results=50

我使用simplexml_load_file

问题是，我该怎么检索

<openSearch:totalResults>9477</openSearch:totalResults>

任何想法?

谢谢

$feedURL = "http://gdata.youtube.com/feeds/api/videos?q=test&orderby=viewCount&start-index=1&max-results=1";
$sxml = simplexml_load_file($feedURL);
$counts = $sxml->children('http://a9.com/-/spec/opensearchrss/1.0/');
$total = $counts->totalResults;
