Getting nth item of array created by performing .split() in ColdFusion 8

Okay, I get that performing the following will create an array of my string split on the _:

<cfset theString = "get_the_point">
<cfset thePieces = theString.Split("_{1}")>

But, how do I get just the 3rd item in the array without having to create a new variable that evaluates the array like:

<cfset theThirdPiece = thePieces[3]>

Is there something to the .Split() that I don't know about that can return just the specific item I'm looking for? This has to be super easy because I didn't find anything in the documentati开发者_如何学Con. Or I was searching it wrong.

If you are using a simple delimiter like the underscore, you can do:

<cfset thePiece = listGetAt("get_the_point", 3, "_")>

All list functions take an optional delimiter argument that is a list of single characters to use as delimiters.

Remember to check the listLen() of the list before attempting to access the nth location.

Just to complete the whole picture I would propose a bit simpler/cleaner way to do what you need -- if you need the last item:

<cfset thePiece = ListLast("get_the_point", "_") />

BTW, looking into the Java-related discussion in the comments of accepter answer I would note that there's a native function for splitting:

<cfset theString = "get_the_point" />
<cfset thePieces = ListToArray(theString, "_") />

I suppose it uses the same Split under the hood.

Just to clarify that it is syntactically correct I should point out that you could also do this:

<cfset lastOne = theString.Split("_")[3] />

I believe this only works in CF9+
