如何合并两个正则表达式的条件

[myricemeli]

目前有两种字符串需要正则表达式验证：

1：

验证文本：A-10-05-02-004
正则表达式：([A,Z])(-)(\d{2})(-)(0[1-9]|1[0-2])(-)(\d{2})(-)(\d{3})

2：

验证文本：A-10-05-B-14-345
正则表达式：([A-Z])(-)(\d{2})(-)(0[1-9]|1[0-2])(-)(\d{2})(-B-)(\d{2})(-)(\d{3})

如何将这两种表达式合并到一起同时验证这两种条件？

([A-Z])(-)(\d{2})(-)(0[1-9]|1[0-2])(-)(\d{2})(-B-)?(\d{2})(-)(\d{3})

引用 1 楼 rayyu1989 的回复:

([A-Z])(-)(\d{2})(-)(0[1-9]|1[0-2])(-)(\d{2})(-B-)?(\d{2})(-)(\d{3})

首先感谢楼上及时回复！！！ 这个组合我之前试过，会产生如下结果： 当配套第一种结果时：A-89-09-0999-000 第三个数字会变成4位 配套第二种结果时当需要显示字母B必须在B的前面键入一个“-”字符。

([A-Z])(-)(\d{2})(-)(0[1-9]|1[0-2])(-)(\d{2})-(B-)?(\d{2})(-)(\d{3})

[q107770540]

简化一下： [A-Z](-)\d{2}\1(0\d|1[0-2])\1(B-)?\d{2}\1\d{3}

3楼正确，感谢！！！
