运行后得到一下字符串
共20页<a class='num' href='http://www.abc.com?&p=0'>首页</a>
<a class='num' href='http://www.abc.com?&p=10'>上一页</a>
<a class='num' href='http://www.abc.com?&p=3'>4</a>
<a class='num' href='http://www.abc.com?&p=4'>5</a>
<a class='num' href='http://www.abc.com?&p=5'>6</a>
<a class='num' href='http://www.abc.com?&p=6'>7</a>
<a class='num' href='http://www.abc.com?&p=7'>8</a>
<a class='num' href='http://www.abc.com?&p=8'>9</a>
<a class='num' href='http://www.abc.com?&p=9'>10</a>
<a class='num' href='http://www.abc.com?&p=10'>11</a>
<span class='current'>12</span>
