Regex 2 digits separated by commas, not all required
I need a regex for the following input:
[2 digits], comma, [two digits], comma, [two digits]
The 2 digits cannot start with 0. It is allowed to only enter the first 2 digits. Or to enter the first 2 digits, then a comma en then the next 2 digits. Or to enter the full string as described above.
Valid input would be:
10
99 开发者_如何学Go 17,56 15,99 10,57,61 32,44,99
Could anyone please help me with this regex?
At the moment I have this regex, but it doesn't limit the input to maximum 3 groups of 2 digits:
^\d{2}(?:[,]\d{2})*$
^[1-9]\d(?:,[1-9]\d){0,2}$
The first part ([1-9]\d
) is simply the first number, which has to be present at all times. It consists of a non-zero digit and an arbitrary second digit (\d
).
What follows is a non-capturing group ((?:...)
), containing a comma followed by another two-digit number (,[1-9]\d
), just alike the first one. This group can be repeated between zero and two times ({0,2}
), so you get either no, one or two sequences of a comma and another number.
You can easily expand the part in the curly braces to allow for more allowed numbers.
^[1-9]\d([,][1-9]\d){0,2}$
