Regex extract string before integer

I have a pack of number say :

the full data always string int string, I use this to split it each group

string1 = ^(.*?)\D+
int2 = (\d+)
string3 = ([a - zA - Z] *$)

but I always gets an error if data only int string (example 123ss), since it's variable string1 reads the first digit, can anybody tell me where did I go wrong?

To match 0 or more non-digit chars at the start of a string you need to define your string1 as

string1 = ^(\D*)

It will capture 0 or more non-digit (\D) chars at the start of the string (^).

The whole string pattern can look like

^(\D*)(\d+)(\D*)$
