[英]Regex to match digits, commas, and specific words
I'm trying to set up regex that would match the following: 我正在尝试设置符合以下条件的正则表达式:
hot 8,6,4,2,1,7
This is the code that I have worked on so far, neither of which are specific enough: 到目前为止,这是我一直在研究的代码,但都不够具体:
^(hot)|(cold)|( )([8])
^(hot)|(cold)|([1-8])|(,\d{1})
Here's the requirements that I need to force a check on format: 这是我需要强制检查格式的要求:
[1-8]
[1-8]
hot
or cold
, there has to be a space and an 8 following the space; hot
或cold
,则必须在其后有一个空格和8; for example, hot 8
or cold 8
hot 8
或cold 8
Some help with this would be immensely appreciated. 在此方面的一些帮助将不胜感激。 Thanks ahead of time!
提前谢谢!
((hot 8,)|(cold 8,))?(/d,)+/d ((hot 8,)|(cold 8,))?(/ d,)+ / d
So I may have miss typed the regex symbols correctly but I'm on a phone and have no quick reference, but I know the rules Exist if that helps. 因此,我可能会错过键入正则表达式符号的正确操作,但是我正在打电话并且没有快速参考,但是我知道规则存在,是否有帮助。 but the explanation is basically..
但解释基本上是..
“hot space number” or “cold space number” (zero or 1 time) then and amount of numbers followed by a comma (1 or more times) then a final number with no finishing comma. 然后是“热空间编号”或“冷空间编号”(零或1次),数量后跟一个逗号(1次或多次),然后是没有结束逗号的最终数字。
Sorry about my answer formatting... mobile device. 抱歉,我的答案格式...移动设备。
