I want to run a comparison across attributes that can be selected by a user during profile creation

I have an application having two forms, one seller form with a list of attribute and the other a buyer form with a list of attributes. I want to create a compare function such that once the buyer uploads a form with any matching attributes to that of the seller, a notification (email and SMS) goes to the seller
