我想把下面代码里的/MusicData/play/201512/5684f44201b44.mp3这个给匹配出来

preg_match('/ url="(.+?)">/', $a, $b);

var_dump($b);

<p><b>这里有一个小例子</b></p>
<pre class="brush:php;toolbar:false"><code class="PHP"><?php $xml = simplexml_load_file("test.xml");

$result = $xml->xpath("//a[@class='play-item' and @url]");

print_r($result);
?></code>

我们可以找到所有a标签class属性为'play-item'且有url属性的元素,然后就是对PHP中SimpleXMLElement类的操作了
