Remove the occurrences of a specified substring (String class)


The Remove intrinsic function removes one or multiple occurrences of a specified substring from the method object (input) string, returning the modified version.

Syntax

%outString = string:Remove( substring, [Count= number])

Syntax terms

%outString A string variable to receive the modified method object (input) string.
string The method object (ie: input) string to which the method is applied.
substring The substring that the method attempts to remove in the method object string. If string contains no occurrences of substring, %outString is set to a copy of string. If substring is null or longer than 256 characters, the request is cancelled.
Count An optional, name-required, argument that is the number of occurrences of substring to remove. Only values greater than 0 are valid. If number is:
  • less than the number of occurrences of the substring, only the first number occurrences are removed.
  • greater than or equal to the number of occurrences of the substring, all occurrences of the given substring are removed.
  • not specified, all occurrences are removed.

Usage notes

  • The search for the target substring is context sensitive; case matters in the attempt to find and remove the target characters.
  • Remove is equivalent to calling Replace method with an empty replacement string argument.
  • Remove is available as of "Sirius Mods" Version 7.3.

Examples

  1. The following request shows two examples of Remove calls against the same input string: the first call removes an occurrence of a specified substring; the second removes both occurrences of a different substring.

    begin %x is longstring %substr is string len 6 %repl is string len 2 %out is longstring %x = 'Remove me' %substr = ' me' %out = %x:remove(%substr) printText {~} is {%out} %substr = 'e' %out = %x:remove(%substr, Count=2) printText {~} is {%out} end

    The request output follows:

    %out is Remove %out is Rmov me
