list

Usage
If you use list functions on strings that are delimited by a delimiter character and a space, a
returned list element might contain a leading space; you use the
spaces from a returned element. For example, consider this list:
<cfset myList = "one hundred, two hundred, three hundred">
To get a value from this list, use the
<cfset MyValue = #trim(listGetAt(myList, 2))#>
With this usage,
element are preserved.
ColdFusion ignores empty list elements; thus, the list "a,b,c,,,d" has four elements.
Example
<h3>ListGetAt Example</h3>
<!--- Find a list of users who wrote messages --->
<cfquery name = "GetMessageUser" datasource = "cfdocexamples">
SELECT Username, Subject, Posted
FROM Messages
