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 (that is, 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:
|
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
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
