Re: [rules-users] Is it possible to Iteriate over a list of string values ?

The Expert documentation states "The expression used to define the object source is any expression that follows regular MVEL syntax." Therefore "from" should be able to use the MVEL syntax for arrays ["one", "two", "three"] however I've not tried and never seen it used. Normally people use "from" to iterate over a dynamic list created elsewhere (another Fact pattern, a global etc). Since you say you need to handle "variable collections" I'd have thought the latter use-case more suitable for yor needs. something like:- when $pch : ParsedCellHolder( ) $val : String( ) from $pch.getStrings( ) then insert( new Fact( $val ) ); end Of course one begs to ask why you don't simply insert the individual values into WM as the spreadsheet is parsed? You'll be doing something like that to either construct the static MVEL in your example or a list. With kind regards, Mike On 9 March 2011 06:19, groovenarula <gnarula1(a)la-z-boy.com&gt; wrote:
