How to valid a logic string

Hi,

We want to display a list of string ( from a object) to let user pick, after they pick some values, for example A, B , C and D, and then user can put some logic for the selection, like (A and B) OR (C and D). My questions are
1. how to valid this logic string?
2. We are going to have a conjunction object to hold the relationship between selectd item with parent, how can we store this logic information?

Thanks,

Jingli

actually the pattern could be like ((A=1) And B ) OR (c=2)
