Question

I asked this question earlier, but it got a negative vote, so I’m rewording it.
I have:

<cfset myExpression = "X">
#REFind(myExpression,myString)#

I need to change myExpression so that it returns a value other than zero if there is NOT an X in myString, and a 0 if there is an X in myString.

Answer 1

<cfset string = "abc" />  
<cfoutput>#refind( "^[^X]+$" , string )#</cfoutput> // 1 

<cfset string = "abcX" /> 
<cfoutput>#refind( "^[^X]+$" , string )#</cfoutput> // 0
