BizTalk Business Rules Engine - Repeating Elements Question
- by Andrew Cripps
Hello
I'm trying to create what I think should be a relatively simple business rule to operate over repeating elements in an XML schema.
Consider the following XML snippet (this is simplified with namespaces removed, for readability):
<Root>
<AllAccounts>
<Account id="1" currentPayment="10.00" arrearsAmount="25.00">
<AllCustomers>
<Customer id="20" primary="true" canSelfServe="false" />
<Customer id="21" primary="false" canSelfServe="false" />
</AllCustomers>
</Account>
<Account id="2" currentPayment="10.00" arrearsAmount="15.00">
<AllCustomers>
<Customer id="30" primary="true" canSelfServe="false" />
<Customer id="31" primary="false" canSelfServe="false" />
</AllCustomers>
</AllAccounts>
</Root>
What I want to do is to have two rules:
Set /Root/AllAccounts/Account[x]/AllCustomers/Customer[primary='true']/canSelfServe
= true IF arrearsAmount < currentPayment
Set /Root/AllAccounts/Account[x]/AllCustoemrs/Customer[primary='true']/canSelfServer
= false IF arrearsAmount = currentPayment
Where [x] is 0...number of /Root/AllAccounts/Account records present in the XML.
I've tried two simple rules for this, and each rule seems to fire x * x times, where x is the number of Account records in the XML. I only want each rule to fire once for each Account record.
Any help greatly appreciated!
Thanks
Andrew
