It works for me on CF 4.0
The snippet:
The snippet:
<cfset mystring ="
<html>
some preceeding
lines to be retained<head>this is the target
head section to be removed
</head><body>... some following
lines to be retained... and so on
">
<cfoutput>
<br> <br> mystring,...|#mystring#|...
<br><br>
</cfoutput>
<CFSET my_string = REreplacenocase(mystring, "<HEAD>.*</HEAD>", "")>
<cfoutput>
<br> <br> my_string...|#my_string#|...
<br><br>
</cfoutput>
Gives (source):
<br> <br> mystring,...|
<html>
some preceeding
lines to be retained<head>this is the target
head section to be removed
</head><body>... some following
lines to be retained... and so on
|...
<br><br>
<br> <br> my_string...|
<html>
some preceeding
lines to be retained<body>... some following
lines to be retained... and so on
|...
