    //采集规则库

    //'规则名' => array('jQuery选择器','要采集的属性'),

//打印结果

print_r($data);

//采集某页面所有的超链接

//可以先手动获取要采集的页面源码

$html = file_get_contents('http://cms.querylist.cc/google/list_1.html');

//然后可以把页面源码或者HTML片段传给QueryList

$data = QueryList::Query($html,array(

    'link' => array('a','href')

    ))->data;

//打印结果

print_r($data);

在线测试采集并查看采集结果 http://querylist.cc/page-Querytest.html
