Answer 2

>((CA|CZ|MU|FM|3U|EU|HU|MF|SC|ZH|8C|8L|BK|G5|KN|HO|JD|9C|CN|KY)[0-9]{3,4})(.*?)([\u4e00-\u9fa5]{1,8})(.*?)([\u4e00-\u9fa5]{1,8})(.*?)([\u4e00-\u9fa5]{1,8})(.*?)([\u4e00-\u9fa5]{1,8})(.*?)￥([0-9]{3,4})(.*?)￥((([0-9]{3,4})(\\+[0-9]{2})?))
这个是我写的正则表达式代码
因为网页是不固定的，当我把源码中的￥符号去掉，匹配时就会出现耗尽cpu  我怀疑是后面的字符串太长导致的
