ReReplace Last Occurance

Can I use ReReplace to replace the last occurance of a pattern with something else.

ie: I want to replace the last occurance of a space with a <br>

The Quick Brown Fox

I want to become

The Quick Brown<br>Fox

which would also work for 1 occurance.

Sorry, should have mentioned how I currently do this.

#Reverse(Replace(Reverse(test)," ",Reverse("<br>")))#

Which works fine, just makes for some unreadable code, thought there might be a simple regular expression method.

PS: I also know how to do this through loops and finds, but I'm after a single statement like above but simpler.
i know u have specifically asked for replacenocase

but just have a look at this

<CFSET var = "The Quick Brown Fox">

<CFSET x = ListGetAt(var,listlen(var,' '),' ')>
<CFSET var = ListDeleteAt(var,listlen(var,' '),' ') & "<br>" & x>

That's probably only marginally easier to read code than my

#Reverse(Replace(Reverse(test)," ",Reverse("<br>")))#

I sometimes show this line of code to potential employees and ask them to tell me what it's doing.

I think there's probably a simple regular expression for this, but i'm not that good at regular expressions.

PS: I specifically asked for REreplace not replacenocase.
PPS: Wouldn't it be nice if Replace had a Scope option of last.
IT Pros Agree: AI and Machine Learning Key

We’d all like to think our company’s data is well protected, but when you ask IT professionals they admit the data probably is not as safe as it could be.


<cfset newtext = reReplaceNoCase(myText, " ([a-z0-9[:punct:]]+)$", "<br>\1")>

will replace the last occurence of a space with a break, if the space is followd by letters, numbers, or a punctuation mark.

[[a-z0-9[:punct:]]+ means one or more letter, number or punctuation mark
$ means "at the end of the text"
<br>\1 is a backreference. Replace the reg ex with a break followed by the expression in parentheses.

If you need to allow other chars behond the space, let me know, should be possible,  too .

Hi again,

one addition:

instead of reReplaceNoCase() you can use reReplace and change the regex to "([a-zA-Z0-9[:punct:]]+)$", but, I think the case insensitive comparison is a bit faster...
