Find all Xpath with wildcard and add to an array

Hello everyone,

I am using Mainframe and Rumba,

I am trying to find all RumbaLabels

This is my absolute path for a textfield with data.
desktop.<RumbaTextField>find("(\"Terminal - Micro Focus Rumba.\")//RumbaScreen//RumbaLabel[@caption='D-12345']"

this is what I came up with so far 

System.out.println(desktop.<RumbaScreen>find("Terminal - Micro Focus Rumba.Screen").find("//RumbaLabel[@caption='D-******']").getText());

I guess I only need to implement a for loop.

Now I need to fetch all "D-XXXXX" elements to an array/list

Could someone help me out?

Regards

Xsi
