Replace last group digits with "*"

Martinsh

There are several group of digit number in a string. I'd like to replace all of the digits in the last group to "*" like following exsamples:

AAA123  --> AAA***

AAA123BBB234CCC  --> AAA123BBB***CCC

AAA123BBB234CCC34567DDD  --> AAA123BBB234CCC*****DDD

How to realize this with skill code? I tried rexReplace() function, but failed.

Regards,

  • Martin,

    pat=pcreCompile("(\\d+)([^\\d]*)$")
dig=pcreCompile("\\d")
foreach(trial list("AAA123" "AAA123BBB234CCC" "AAA123BBB234CCC345DDD" "TEST123MORE5678OTHER")
  result=pcreReplace(pat trial "***\\2" 1)
  printf("%s -> %s\n" trial result)
  replacement=pcreReplace(dig pcreSubstitute(pat "\\1\\2") "*" 0)
  result=pcreReplace(pat trial replacement 1)
  printf("VARIABLE *: %s -> %s\n" trial result)
)

    The second approach is if you want the number of * to be the same as the number of digits - ah, I see you edited the post to give that example (I wrote the code without having seen the edited post). rexReplace() is very basic, so using the pcre functions makes much more sense.
