How to validate a node list using business rules

Question

Hello everybody:
I'm developing with Oracle SOA Suite 11.1.1.6
I'm using business rules to check some business requirements from my processes and I am having a situation that I like to share with you in
order to receive some advices to solve it.
In the rule input variable I have an element with the following structure (example):
[code]
<User>
    <Name>Big Boss</Name>
    <ExpertiseLevel>10</
ExpertiseLevel>
     <DepCode>RRHH</DepCode>
    <AssignedUsers>
        <User>
            <Name>Roman</Name>
            <ExpertiseLevel>5</ExpertiseLevel>
            <DepCode>RRHH</DepCode>
             </AssignedUsers>
        </User>
        <User>
            <Name>Mark</Name>
            <ExpertiseLevel>2</ExpertiseLevel>
            <DepCode>RRHH</DepCode>
             </AssignedUsers>
        </User>
        <User>
            <Name>Jane</Name>
            <ExpertiseLevel>5</ExpertiseLevel>
            <DepCode>RRHH</DepCode>
             </AssignedUsers>
        </User>
        <User>
            <Name>Lisa</Name>
            <ExpertiseLevel>3</ExpertiseLevel>
            <DepCode>FNZ</DepCode>
             </AssignedUsers>
        </User> 
    </AssignedUsers>
</Request>
[/code]
Using business rule I need to check that all the users departament code *<DepCode>* match with an specified code, besides another
validations. As it's showed in the previous XML I have a user list inside the *<User>* node and I have to use a loop to check all the users
assigned to the Big Boss user. My question is: Which could be the most "efficient" way to make that loop?
I have been thinking in some options:
1- Create a ruleset for users validation and make the loop inside the process executing the user ruleset many times as users exist?
2- Using functions (but this is not an option because I have a requirement that forbid to use functions inside the business rules
implementation)
Could anybody tell me how can I use the foreach available in the ruleset advanced mode? Can I execute a desicion table in a loop?
Thanks in advance

hi
I guess you will need a CX.
when user enters a value to the node,your CX will get fired.
it will take the current value and check with your database.if value already exists then you have to empty that node in the CX. and show a message that you needs to change the value of node.
Let me know if you need code.
send a mail on [email protected]
I will provide you the code.
