cfloop: looping over a list or file
Description
Looping over a list steps through elements contained in any of these entities:
• A variable
• A value that is returned from an expression
• A file
Syntax
<cfloop
index = "index_name"
list = "list_items"
delimiters = "item_delimiter">
...
</cfloop>

Attributes
Example
This loop displays four names:
<cfloop index = "ListElement"
list = "John,Paul,George,Ringo">
<cfoutput>#ListElement#</cfoutput><br>
</cfloop>
You can put more than one character in the delimiters attribute, in any order. For example, this
loop processes commas, colons, and slashes as list delimiters:
<cfloop index = "ListElement"
list = "John/Paul,George::Ringo"
delimiters = ",:/">
<cfoutput>#ListElement#</cfoutput><br>
</cfloop>
ColdFusion skips the second and subsequent consecutive delimiters between list elements. Thus,
in the example, the two colons between "George" and "Ringo" are processed as one delimiter.
To loop over each line of a file, use the tag this way:
<cfloop list="#theFile#"
index="curLine"
delimiters="#chr(10)##chr(13)#">
...
</cfloop>
