Combine specific branches into 1 branch

[ruud.vanknippenberg (RV)]

Hi,

Question,

There are 2 lists;

List A contains lines, subdivided into branches {0} {1} … {13}

List B; contains branches, with items. The items refer to the list branches in list A.
so item: 0 (in list B) --> branch {0} list A
so item: 1 (in list B) --> branch {1} list A
so item: 2 (in list B) --> branch {2} list A
etc.
List A:

ListB:

I would like to generate a new list C;

1. With the same branch structure as list B
2. But instead of the items, it contains the corresponding lines of list A

so list C would like like;
{0}
Lines present in list A in branch {0}
{1}
Lines present in list A in branch {1} + {2}
{2}
Lines present in list A in branch {3}
{3}
Lines present in list A in branch {4} + {5}
…

All of your threads look the same, is there a pattern here? Something common to all of them?
