Business Service to fetch property value for dynamic message

Dynamic Message- Message where certain XML elements might or might not be available.

Assume incoming message might or might not have XML Element "Contact_Business Address"(Contact_undBusiness_spcAddress in xml example shown below). If we have a XML element we need to retrieve the value of attribute "Country" and if its value is USA we need to set it.

We were not able to use "PRM ANI Utility Service" and "Workflow Utilities" business service here as it throws error if XML Element "Contact_Business Address" is not found in the incoming message.

We have used business service to retrieve same. Please find the code written in BS below:

Input of Business Service

if(MethodName=="Execute")

{

            try

            {

                        var PropVal = "";

                        var NumChilds = 0;

                        var psListOfContact = Inputs.GetChild(0);

                        var psContact = psListOfContact.GetChild(0);

                        var psListOfConAddr = psContact.GetChild(0);

                        NumChilds =psListOfConAddr.GetChildCount();

                        for (var i = 0; i < NumChilds; i++)

                        {

                                    var psAddr = psListOfConAddr.GetChild(i);

                                    var Type = psAddr.GetType();

//Check if the type exists then only fetch the value else skip this part.

                                    if(Type == "Contact_Business Address")

                                    {

                                                Outputs.SetProperty("Type", Type);

                                                PropVal = psAddr.GetProperty("Country");

                                                if(PropVal == "USA")

                                                {

                                                Outputs.SetProperty("Country", PropVal);

                                                }

                                    }

                        }

                        return (CancelOperation);

            }

            catch(e)

            {

                        throw(e);

            }

            finally

            {

                        psAddr= null;

                        psListOfConAddr= null;

                        psContact= null;

                        psListOfContact= null;

            }

            return (ContinueOperation);

}
