[SR-Users] Striping Character from $rU

[dotnetdub]

Hi,

Running 1.53 and also 3.01

I know there are operators to strip() and strip_tail() to remove characters
from the front and end of a uri - what would people recommend to make sure
that the uri only ever contains numerical value?

If I wanted to for example strip the - character what would be the best way?

TIA.
Stephen.
