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.

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

Parameters

Parameter

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

For details on using regular expressions, see "Using Regular Expressions in Functions" in the ColdFusion Developer's Guide.
