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.

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").

For details on using regular expressions, see Chapter 7, "Using Regular Expressions in Functions," in ColdFusion MX Developer's Guide.

<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.
