Regular expression question

Question

Please help me construct a regex to match:

some text(x, x, x, x)

where x can be any integer either positive or negative.

I need it to match exactly as it is shown above. Each x can be a different positive or negative integer.

Answer 1

Try something like this:

[^(]+\(\s*-?\d+(\s*,\s*-?\d){3}\s*\)

Answer 2

that exactly would be /text((-?\d+,?){,3})/

or more generally /^\w+((-?\d+,?)+)/
