REReplaceNoCase

Description

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

Return value

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.

Syntax

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

History

New in ColdFusion MX: 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").

Parameters

Parameter Description

string
A string or a variable that contains one.

reg_expression
Regular expression to replace. For more information, see Developing ColdFusion MX Applications with CFML.

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.

Parameter	Description

To include a backslash character in a parameter of this function, you must precede it with another backslash, as an escape character.

Example

<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")#
