The string change activity offers the delphi stringutils functions to change a string.
Activity properties
Retrurn value is optional in some change functions.
If return value is selected, a new string with the changed value is created.
If return value is not selected, the old string is changed.
Possible change functions:
Adds quotes to the beginning and end of a string;
Example:
String: "The quick brown fox jumps over the lazy dog."
begin var ChangedString: string; ChangedString := StringValue.QuotedString; end; |
Result = "'The quick brown fox jumps over the lazy dog.'"
Removes the quotes from a string at the beginning and the end if present.
Example:
String: "The quick brown fox jumps over the lazy dog.'"
begin var ChangedString: string; ChangedString := StringValue.DeQuotedString; end; |
Result = "The quick brown fox jumps over the lazy dog."
Inserts a string into a string at a given position.
Example:
String = "The quick brown fox jumps over the lazy dog."
String to insert = "test"
Position = 2
begin var ChangedString: string; ChangedString := StringValue.Insert(2, 'test'); end; |
Result = "Thteste quick brown fox jumps over the lazy dog."
Joins an array string with a separator.
Example:
Array = ['the', 'quick', 'brown'];
Separator = -
Position = 1
Number of ietms = 2
begin var ChangedString: string; var ArrayToJoin := StringArray; ChangedString := String.Join('-', ArrayToJoin, 1, 2); end; |
Result = "quick-brown"
Separator is optional
Postion is optional with a default of 0
Number of items is option with a default of everything after position.

Replace all = True
Ignore case = False
begin var ChangedString: string; ChangedString := StringValue.Replace('-', ' ', [rfReplaceAll]); end; |
Result = "the quick brown"
