产品型号和代码的正则表达式代码

Question

我找到了一个非常有用的正则表达式代码，以便提取产品代码here，这就是表达式：

\b((?:[a-z]+\S*\d+|\d\S*[a-z]+)[a-z\d_-]*)\b

它几乎完美无缺，但我只需要检测并提取长度至少为5位的产品代码。

For example, for the following strings:

5T COFFEE BREW FOR BLACK & DECKER DCM-601B
10T COFFEE BREW FOR BLACK & DECKER DCM-1100B
10T COFFEE BREW FOR BLACK & DECKER DCM-1100W

I get:

Desired outcome:

我该怎么做？

Answer 1

如果我们假设您的代码包含5个或更多非空白符号，并且必须至少有1个数字，则代码的正则表达式为：

\b(?!\d+\.\d+)(?=\S*\d)\S{5,}\b

请参阅Demo 1

(?!\d+\.\d+)不允许使用1.2345或12.44等浮动/十进制数字。

Answer 2

我不太确定我是否理解了您的问题，但您可以使用这样的正则表达式来获取您想要的产品代码：

((?:\w{2,}\.)?\w{1,}[.\/-]?\d+\w+)(?=\b)
