StringRegExp pattern help

[roofninja]

I am having problems with understanding StringRegExp. The example doesn't help me, but get me more confused. I don't seem to have that pattern correct.

This is what I am trying to do. I have a folder that I am trying to check to see if it has only numbers and dots or periods in it. It doesn't matter in what order just as long it contains only numbers and dots.

$a = StringRegExp(10.0.648.133,"\d.\d.\d.\d")

$a = StringRegExp($userInput, "[{0-9}]|[.]")

"^(?:\d|\.)+\z"

Thanks for the help. I don't know why, but I have never figured out StringRegExp. Solved.

Just for the record

Here is another one

"^[0-9.]+$"
