Regular expression for matching hw:n,n

Question

Can someone help me with a regular expression for matching hw:n,n?

where n is any number between 0-9.

an example string would be hw:0,1

Thanks.

Answer 1

That is very simple, just use the digit identifier \d:

hw:\d,\d

The above regex might also match other numerals, such as the arabic ones (see: https://stackoverflow.com/a/6479605/1105858)

If you want to limit to the actual 10 digits 0–9, you can use it as a character class:

hw:[0-9],[0-9]

Answer 2

you can try this

hw:[0-9]+,[0-9]+

[0-9]+: matches one or more digits

,: matches a comma
