array processing on ES501

Hi…

I am using Enterprise Server 5.0.1. In my integration component, if I have say an array of strings and I need to filter out some records. How do I process it so that I have an output which is an array without those filtered records.

Something like in_array : length 10 and out_array = 8?

Do I use a map step, custom code?

I’m stuck on this for days…could someone please help… thanks!
