[kepler-users] List handling

[Jianwu Wang]

Hi Hector,

     There are at least two options:

     1) Use "Iterate over array" actor, which you can put your 
sub-workflow into the actor to process each element in the array. The 
output of this actor is still an array.

     2) Use "Array To Sequence" actor to transform your array to a 
sequence of tokens before being processed.

     I made a demo workflow at 
https://code.kepler-project.org/code/kepler/trunk/workflows/iterateOverArray/IterateOverArray.xml, 
which use the above both actors. Please have a look.

Best wishes

Sincerely yours
