I’m so used to dealing with comma-delimited lists in ColdFusion that I would sometimes take a data file that had one item per line and replace the newline characters with commas.<\/p>\n

It’s easy to use the carriage return [chr(13)] and line feed [chr(10)] characters as list delimiters, though, and remove the intermediary step. Here’s a quick example:<\/p>\n

<cfsavecontent variable=\"data\">\r\nthis\r\nis\r\na\r\nlist\r\nwith\r\none\r\nword\r\nper\r\nline\r\n<\/cfsavecontent>\r\n\r\n<cfoutput>\r\n    <ol>\r\n        <cfloop list=\"#data#\" delimiters=\"#chr(13)##chr(10)#\" index=\"line\">\r\n            <li>#line#<\/li>\r\n        <\/cfloop>\r\n    <\/ol>\r\n<\/cfoutput><\/code><\/pre>\n
Which produces the following:<\/p>\n
    \n
  1. this<\/li>\n
  2. is<\/li>\n
  3. a<\/li>\n
  4. list<\/li>\n
  5. with<\/li>\n
  6. one<\/li>\n
  7. word<\/li>\n
  8. per<\/li>\n
  9. line<\/li>\n<\/ol>\n
