由连字符分隔的字母数字正则表达式模式

Question

我有一组由连字符分隔的ID，其中至少可以有6个字符，包含字母数字值和一些特殊字符，在末尾，只有数字值是不允许的。如下所示：

YUIO-10GB-BG4   ==> Should match

U-VI1.1-100-WX-Y9  ==> Should match

1-800-553-6387  ==> Shouldn't match because all are digits

T-Series  ==> Shouldn't match as all only 2 letters are capital

我正在尝试下面给出的具有以下规则的以下模式，但面临一些测试查询的困难...

((?=\S{6,})[A-Z]{1,}(([A-Z0-9./+~]+){0,}-){1,}[A-Z0-9./+~]+=*)

Answer 1

您可以使用以下正则表达式来获取所有匹配项，然后过滤掉那些不包含带有正则表达式的字母的匹配项：

/(?:^|\s)(?=\S{6,})(?=\S*[A-Z])([A-Z0-9./+~]+(?:-[A-Z0-9./+~]+)+=*)(?!\S)/g

请参阅正则表达式演示。

详细信息

• （？：^ |\s）-字符串或空格的开头
• （？=\S{6，}）-6个或更多字符
• （？=\S*[A-Z]）-0个非空白字符后必须至少有1个大写ASCII字母
• <代码>（[A-Z0-9./~]（？：-[A-Z0-9./~]）=*）-第1组：
  • [A-Z0-9./~]-1大写ASCII字母，数字，，/，，~
  • <代码>（？：-[A-Z0-9./~]）-1出现：
    • 一个字符
    • [A-Z0-9./~]-1大写ASCII字母，数字， ，/，，~
