substitute

Replace text by content (substring matching).

Syntax

v = substitute(text, old_text, new_text, instance_num)

Description

Returns text with old_text replaced by new_text. Without instance_num, replaces every occurrence; with it, replaces only the instance_num-th occurrence (1-based).

Examples

substitute('1-2-3-4', '-', '/')         % '1/2/3/4'
substitute('1-2-3-4', '-', '/', 2)      % '1-2/3-4'
