regex validation

[Carina4]

Hi! I've a question for my regex validation, I need to validate that the // or \\ can be inserted in the rest of the string but not at the first character.

I'm working with this regex but not allowed // or \\ at the rest of sentence.

Can somebody help me with my regex?

This is my expression regex = /^[A-Z0-9./]([A-Z0-9\-.()\s]{1,2}[A-Z0-9\-./()\s]?)*$/;

Thanks a lot!
