Description
Replaces occurrences of a substring within a string.
StringReplace replaces occurrences of the substring specified by OldPattern with the substring specified by NewPattern in the string Source.
Flags is a TReplaceFlags type parameter. If rfIgnoreCase is set, the replacement is case-insensitive; otherwise case is significant. If rfReplaceAll is on, all occurrences of OldPattern are replaced; if not, only the first occurrence is replaced.
Note: This function is designed for UnicodeString variables. To work with AnsiString variables, use the System.AnsiStrings.StringReplace function. To work with WideString variables, use the System.WideStrUtils.WideStringReplace function.
Note: Recursive replacement of substrings is not supported. This means that if the substitution of OldPattern results in a new match for NewPattern, that match is not replaced.
To replace all occurrences of the substring within the string, you may also use the ReplaceStr function to do a case-sensitive search, or ReplaceText to do a case-insensitive search.
