I want to find longest possible string which include above given two patterns and return starting and finishing index of the array.

I try many code sample, but I can't find suitable code
So if you can please help me.....

F.e. Regular Expression Like: "XX+ZZ+" which would return

First match: XXZZ
Second Match: XXXXZZZZZZ
