<cfset ny="amar, powar">
<cfset indi=REReplaceNoCase("my <name> is <amar>","</?(#ListChangeDelims(ny,"|")#)[^ >]*>","","ALL" )>
<cfoutput><br>"ind1 " #indi# <br></cfoutput>

Output of above code is " my is"

Why it is replacing "<name>" even it isn't present in lis?

Thanks

    because the browser thinks those angle brackets indicate an html tag. cfdump your variable to troubleshoot your code.

    The ? means that the character or group preceding it is optional or more correctly means that there can be one or none of them. It can also be used to signify that a match should not be greedy but it is not being used in this case. I suggest getting a book on Regex. It is essentially quite straight forward once you know the syntax but it is very powerful and if you are doing any string manipulation it is a must to know well!
