如何获取字符串中最后一个a标签href的值

String = " </a>   <b>1</b>
 <a href="/news/201804/28/207901_2.html" target="_blank" rel="external nofollow"  target="_blank" rel="external nofollow" >2</a>
 <a href="/news/201804/28/207901_3.html" target="_blank" rel="external nofollow" >3</a>
 <a href="/news/201804/28/207901_4.html" target="_blank" rel="external nofollow" >4</a>
 <a href="/news/201804/28/207901_5.html" target="_blank" rel="external nofollow" >5</a>
 <a href="/news/201804/28/207901_6.html" target="_blank" rel="external nofollow" >6</a>
 <a href="/news/201804/28/207901_2.html" target="_blank" rel="external nofollow"  target="_blank" rel="external nofollow" >下一页 "
           

使用Java中String类的split方法拆分：

String[] split = String.split("href=\"");

String  value = split[split.length-1];

System.out.println("value = " + value);

输出结果：value = "/news/201804/28/207901_2.html"
