How to implement complex xpath logic in Interface determination

Hi Team,

I have a requirement like based on different values combinations i need to map to two different target structures.

First Input Values:

2553

2554

2556

Second Input Values:

01

02

03

Third Input Values:

2557

2558

if the combination of first input and second input then it has to map to one target structure

eg:

2553 01 then map to pack structure

2554 02 then map to pack structure

if the combination of third and first inputs then it has to map to different target structure

eg:

2557 01 then map to Back structure

2558 02 then map to Back structure

kindly help me to resolve this issue.

Thanks & Regards

Swathi
