Reg-ex适用于城市和街道 [英] Reg-ex for city and street

问题描述

CITY的RegEx：我们将要求有2个字母字符且没有数字字符。



STREET的正则表达式：有2个连续的字母字符，
或一个数字和一个alpha，

或一个数字和一个数字，

或一个字母和一个字符串



我尝试了什么：



城市和街道的注册表





有2个连续的字母字符

解决方案

对于城市，请尝试：

 ^ [a-zA-Z] {2，} 

但......St.Louis？ 纽约？您可能希望扩展您的规格。

同样，街道充满了问题：空间非常普遍，第42街非常可能，等等。您可能不希望使用正则表达式中的任何一个 - 有太多的边缘情况会让用户试图输入他们 知道 的数据是正确的但是你的规则不接受。



对于城市，我会使用列表（或自由文本），我允许自由文本的街道。

RegEx for CITY: we will require that there be 2 alpha characters AND no numeric characters.

Regex for STREET :have 2 consecutive alpha characters,
or a number and an alpha,
or a number and a number,
or an alpha and a string

What I have tried:

Reg Ex for City and Street


to have 2 consecutive alpha characters

解决方案

For city, try:

^[a-zA-Z]{2,}

But ... "St.Louis"? "New York"? You might want to expand your specification.
Similarly, streets are fraught with problems: spaces are very common, "42nd St." is very possible, and so forth. You probably don't want to use a Regex for either of these - there are too many "edge cases" which will frustrate users trying to enter the data they know is correct but your rules don't accept.

For cities, I'd use a list (or free text), for streets I'd allow free text.
