正则：    public static void getNext() {
        String html = "<a href=\"http://www.tianya.cn/publicforum/content/free/1/2636064.shtml\">10</a>\n"
                + "<a id =\"1\" href=\"http://www.tianya.cn/publicforum/content/free/1/2634838.shtml\">下一页</a>\n"
                + "<a href=\"http://www.tianya.cn/publicforum/content/free/1/2634838.shtml\" name=\"a\">下一页</a>\n"
                + "<a href=\"http://www.tianya.cn/publicforum/content/free/1/2644117.shtml\">末页</a>\n"
                + "<a href=\"#adsp_content_replybox_frame_1\">回复此贴</a>\n" + "<span>共41页</span>\n";
        Pattern pattern = Pattern.compile("<a\\s+.*?href=\"([^\"]+)\"[^>]*>下一页</a>");
        Matcher matcher = pattern.matcher(html);
        while (matcher.find()) {
            System.out.println(matcher.group(1));
        }
