Substitutables	`aString`, `replacement`	Can be any variable or object attribute having the type String.
	`regExpPattern`	Regular expression (see Regular Expressions for a list of valid regular expressions). An introduction into regular expressions can be found at http://www.regular-expressions.info/.

Examples	set changed = stringSet.s1.replace("X.+", "A");

Trimming spaces and whitespaces

If you want to trim leading or trailing spaces or whitespaces of a string, you can use regular expressions in order to remove them.

Trimming leading spaces	set trimmedString = stringSet.s1.replace("^[ ]+", "");
Trimming trailing spaces	set trimmedString = stringSet.s1.replace("[ ]+$", "");
Trimming leading and trailing spaces	set trimmedString = stringSet.s1.replace("^[ ]+\|[ ]+$", "");
Trimming leading spaces and whitespaces (\t)	set trimmedString = stringSet.s1.replace("^[ \t]+", "");
