Find repetition with regex

Question

I would like to catch with regex any repetition of these three characters . / -

For example I would like to find:

"a//fsdf"
"a/-fd"
"v.-"

But not this one:

"a/f.d-qwe"

Answer 1

You mean like this one? :

[\.\/\-]{2,}

Here are the test results

Answer 2

Use curly braces, to specify the amount of repetition:

[./-]{2,}

This will match the string of characters with length exceeding 2.
