REReplaceNoCase

Description

Uses a regular expression to search a string for a string pattern and replace it with another. The search is case-insensitive.

Returns

If scope = "one": returns a string with the first occurrence of the regular expression replaced by the value of substring.
If scope = "all": returns a string with all occurrences of the regular expression replaced by the value of substring.
If the function finds no matches: returns a copy of the string, unchanged.

Function syntax

REReplaceNoCase(string, reg_expression, substring [, scope ])

History

ColdFusion MX: Changed behavior: this function inserts the following special characters in regular expression replacement strings, to control case conversion: \u, \U, \l, \L, and \E. If any of these strings is present in a ColdFusion 5 application, insert a backslash before it (for example, change "\u" to "
u").

Parameters

Parameter	Description
string	A string or a variable that contains one.
reg_expression	Regular expression to replace. For more information, see Using Regular Expressions in Functions in the Developing ColdFusion Applications.
substring	A string or a variable that contains one. Replaces reg_expression.
scope	one: replaces the first occurrence of the regular expression. Default. all: replaces all occurrences of the regular expression.

Usage
