Question

how could I do something like that:

Input:

+93120nvsenr++ +++:LKK213ll

Output:

selected all non digits and all “+” except “+” which is first and start the string

Example:

+312313__3fffa“`+++31+3

Final result after String.replaceAll(regex, "") should be [phone]

So far my regex is:

[^\\d^+]

which is: ignore all non digits and all “+” signs and gives me:

+3123133+++31+3

Answer 1

You can use this regex

(?!^\+)\D+
    ^
    |
    |->this would replace a non digit character only if it doesn't have a +( which is at the beginning of the string) that preceed's it
