StringReplace function

Returns a string with occurrences of one substring replaced by another substring.

Unit

SysUtils

Category

string handling routines

type
TReplaceFlags = set of (rfReplaceAll, rfIgnoreCase);
function StringReplace(const S, OldPattern, NewPattern: string; Flags: TReplaceFlags): string;

Description

StringReplace replaces occurrences of the substring specified by OldPattern with the substring specified by NewPattern. StringReplace assumes that the source string, specified by S, may contain Multibyte characters.

If the Flags parameter does not include rfReplaceAll, StringReplace only replaces the first occurrence of OldPattern in S. Otherwise, all instances of OldPattern are replaced by NewPattern.

If the Flags parameter includes rfIgnoreCase, The comparison operation is case insensitive.

Espero te sirva.
