RegEx has always been my Achilles' heel. I am writing web app, where user will input his identifier. I'm using RegexValidator to validate this input.
RegEx一直是我的阿喀琉斯之踵。我正在编写web应用程序，用户将输入其标识符。我正在使用RegexValidator验证此输入。
The identifier should be something like this:
标识符应该是这样的：
TN-In-PL-KW-2012-1234
And this is how the identifier is built:
这就是标识符的构建方式：
- first two letters are always
TN - 前两个字母总是TN
- followed by hyphen
- 其次是连字符
- then two letters, that are either:
In,Te,YoorEt - 然后是两个字母，分别是：In，Te，Yo或Et
- hyphen
- 连字符号
- two uppercase letters
- 两个大写字母
- another hyphen
- 另一个连字符
- another two uppercase letters
- 另外两个大写字母
- hyphen
- 连字符号
- four digits, that are a year, so something between 1970 and 2012 (I can ignore that as long as there are 4 digits)
- 四位数，即一年，所以在1970年到2012年之间（只要有4位数，我可以忽略它）
- hyphen
- 连字符号
- ordinal number that can have from 1 to 4 digits
- 序号，可以是1到4位数
Please help me writing RegEx to match this identifier.

TN-（在|特|哟| ET） - （[AZ] {2} - ）{2}（19 [7-9] [0-9] | 200 [0-9] | 201 [0-2] ） - [0-9] {1,4}
