REReplaceNoCase

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

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.

String functions

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

REFind, REFindNoCase, Replace, ReplaceList

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, you must insert a backslash before it (for example, change "\u" to "\\u").

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 Developing ColdFusion MX Applications.
substring	A string or a variable that contains one. Replaces `reg_expression`.
scope	`one`: Replace the first occurrence of the regular expression. Default. `all`: Replace all occurrences of the regular expression.

For details on using regular expressions, see Using Regular Expressions in Functions in Developing ColdFusion MX Applications.

<p>The REReplaceNoCase function returns <i>string</i> with a regular 
expression replaced with <i>substring</i> in the specified scope. 
This is a case-insensitive search.
<p>REReplaceNoCase("cabaret","C|B","G","ALL"):   
<cfoutput>#REReplaceNoCase("cabaret","C|B","G","ALL")#</cfoutput>
<p>REReplaceNoCase("cabaret","[A-Z]","G","ALL"):   
<cfoutput>#REReplaceNoCase("cabaret","[A-Z]","G","ALL")#</cfoutput>
<p>REReplaceNoCase("I LOVE JELLIES","jell(y|ies)","cookies"):   
<cfoutput>#REReplaceNoCase("I LOVE JELLIES","jell(y|ies)","cookies")#
</cfoutput>
<p>REReplaceNoCase("I LOVE JELLY","jell(y|ies)","cookies"):   
<cfoutput>#REReplaceNoCase("I LOVE JELLY","jell(y|ies)","cookies")#

It isn't immediately obvious that you can use backreferences in the substring to replace as well, e.g. REReplaceNoCase( "hello goodbye", "(hello)", " ", "all" )

It's certainly nice though.
