I am trying to create an expression that will accept / and - characters, like this 123/12-125 (must accept / and -).
I attempted to write a ValidationExpression as follows: "^(\d*\/?\d*)^(\d*\-?\d*)$", but it did not work.
The '/' or '-' will be in the middle of the string with single occurrences multiple times. Both characters are optional.
For example:
12/321/1122122-9-666/9995
The regular expression "^(\d+([\/\-]\d+)+)$" is effective. I have personally tested and confirmed its functionality.
If you need to ensure that all required digits match:
"^(\\d{3}\\/\\d{2}\\-\\d{3})$"
If you require 123/12 and -125 is optional
"^(\\d+\\/\\d+)(\\-\\d+)?$"
and so on
In many programming languages, the backslash \ can be misinterpreted in regular expressions. To use it properly, you must double it as \\. For example, use \d +.
Additionally, use * for options that may or may not occur, and use + for mandatory occurrences.
Lastly, remember that ^ should only be used at the beginning of a "sentence". It can also be used within a group as a negation like [^ az], but be cautious as it accepts "anything that is not ...".
Test your regular expression here:

This tool will show you exactly what matches your expression.
You can also organize match groups like this:
"^(\d+([\/\-]\d+)+)$"
This pattern means:
