運行后得到一下字符串

共20頁<a class='num' >首頁</a>
<a class='num' >上一頁</a>
<a class='num' >4</a>
<a class='num' >5</a>
<a class='num' >6</a>
<a class='num' >7</a>
<a class='num' >8</a>
<a class='num' >9</a>
<a class='num' >10</a>
<a class='num' >11</a>
<span class='current'>12</span>
<a class='num' >13</a>
<a class='num' >14</a>
<a class='num' >15</a>
<a class='num' >16</a>
<a class='num' >17</a>
<a class='num' >18</a>
<a class='num' >19</a>
<a class='num' >20</a>
<a class='num' >下一頁</a>
<a class='num' >尾頁</a>
