exacttarget - LookUpRows on rowset created with function BuildRowSetFromString -

is possible apply function lookuprows or lookup array created buildrowsetfromstring?

i have this:

set @rowset = buildrowsetfromstring(@itemsstring2, '|') 

i'd know if there's function on can do:

set @var = lookuprows(@rowset, item_id, ... )  

i trying using loop. want know if there's function can this.

no. wish.

best bet use arrays in server-side javascript or possibly gtl.

if want over-engineer it, can use xml , xpath array functions in ampscript. i've written use-case examples here on personal blog.

also, there lot more sfmc dicussion going on over in http://salesforce.stackexchange.com.
