用QueryList采集金山词霸《每日一句》

采集金山词霸的每日一句，需要说明的是，并不能直接匹配出音频的地址，匹配出来的是类似于这样个字符串：
iciba_common_top_onSecondDelay('http://news.iciba.com/admin/tts/2015-02-27.mp3');
所以需要用个回调函数来过滤出音频地址。

1. [代码][PHP]代码    

<?php
require '../QueryList/QueryList.class.php';

$url = 'http://news.iciba.com/dailysentence';
$reg = ".pic";
$rang = array(
        //匹配英文
        "en" => array(".en>a","text"),
        //匹配中文
        "cn" => array(".cn>a","text"),
        //匹配音频
        "audio" => array(".sound","onmouseover",'',function($v,$k){
                                //回调函数，用于匹配出音频地址
                                if(preg_match('/http[^\']+/',$v,$arr))
                                {
                                    $v = $arr[0];
                                }
                                return $v;
                         }),
        //匹配图片
        "pic" => array("a:eq(0)>img","src"),
        //匹配页面地址
        "page" => array("a:eq(0)","href")
    );
$data = QueryList::Query($url,$rang,$reg)->jsonArr[0];
print_r($data);

2. [代码]采集结果    

Array
(
[en] => Courage is not the absence of fear, but rather the judgement that something else is more important than fear.
[cn] => 勇者并非无所畏惧，而是判断出还有比恐惧更值得重视的东西。
