I need to use array elements while pattern matching.

 @myarr = (ELEM-1, ELEM-2, ELEM-3,ITEM-1,ITEM-2,ITEM3);

ELEM-1, ELEM-2, ELEM-3,ITEM-1,ITEM-2,ITEM3 are the distinct column values from a file which I read in beginning of my scripts and store them in @myarr.

Basically What I intend to do is

1. If my @myarr = (ITEM-1,ITEM-2,ITEM3) ==> I print all the information from items.txt file.

2. If my @myarr = (ELEM-1, ELEM-2, ELEM-3) ==> I print all the information from elem.txt file.

3. If my @myarr = (ELEM-3,ITEM-1,ITEM-2,ITEM3)

==> I want to print all the information from items.txt file + Some few lines for elem.txt (Based on Pattern Match in file with keyword ELEM-3 in @myarr)

I am able to code the things for 1 and 2 but not not able to achieve my Point 3 If my @myarr = (ELEM-3,ITEM-1,ITEM-2,ITEM3)

I need a generic code instead of hardcoding the array elements inside the code since array elements are not known & may vary.

Thanks in advance.
