This tutorial describes how to write a script that finds and replaces every instance of a certain substring within a string, with another string.
An example implementation can be found here.
Script
This script requires three variables:
(i)— the primary loop variable(j)— the secondary loop variable(output)— the output string
define replace (substring) with (replacement) in (string)
set [output v] to []
set [i v] to (1)
set [j v] to (1)
repeat until <<(i) > (length of (string))> and <(j) = (1)>>
if <(letter (i) of (string)) = (letter (j) of (substring))> then
change [j v] by (1)
if <(j) > (length of (substring))> then
set [output v] to (join (output) (replacement))
set [j v] to (1)
end
else
if <(j) > (1)> then
change [i v] by ((1) - (j))
end
set [output v] to (join (output) (letter (i) of (string)))
set [j v] to (1)
end
change [i v] by (1)
end
