Listview with scrollbar, how to scroll down and identify some items matching with a patern ?

Hello,
 I'm completely new with Sikuli and would need your help...
I have a listview of 100 items but only 10 of them are visible..to show the other, scrolling down is required..
I have two questions :
How to make Sikuli running a certain set of action for each and every item complying with the condition : contains "#" ?
How to make Sikuli scrolling down and ensure all the 100 items are seen by Sikuli ?

Thanks,
Christophe
