1. 改进jsonPath,jsoup,xpath中的规则切分方法,允许查询规则的正则或字符串中存在“&&”,“||”,“%%”而不切错。

----------------------

2. 加强AnalyzeByJSoup中的索引写法

    /**
     * '.'开头表示选择元素,或'!'开头排除那些元素。两者都支持以索引列表按顺序指定元素列表
     * ':'分隔不同索引或区间
     * 区间格式为 start~end+step,其中start为0可省略,end为-1可省略。
     * 索引,区间两端及间隔都支持负数
     * 例如 tag.div.-1:3~-2+-10:2
     * 特殊用法 tag.div.-1~0 可在任意地方让列表反向
     * */

 -------------------
 已经测试三天没发现大问题,坤飞大大可以再测试看看
