Hi,
I am developing a message flow where:
1. Input Message is CSV File like this:
USD,16/02/2004,2.5974,N
GBP,16/02/2004,1.3776,N
INR,16/02/2004,117.5455,N
AUD,16/02/2004,3.2833,N
2. I have created a message set as
CurrencyRates
|
+CurrencyRate (Multiple occurrences)
|
Currency (For e.g, USD)
Date (For e.g.,16/02/2004)
Rate (For e.g., 2.5974)
FixedRate ('N')
3. I have created TDS1 and XML1 physical formats for This input message.
4. I have set my MQInput Node to MRM domain,TDS1 Format and CurrencyRates Message Type, to accept the CSV File.
5. Then I added a compute Node to change the Message Fromat from TDS1 to XML1 (Reference : SWIFT_To_XML Sample) as follows:
| Code: |
SET OutputRoot = InputRoot;
SET OutputRoot.Properties.MessageFormat = 'XML';
|
6. Then I added the ResetContentDescriptor node. I set all the properties correctly.
7. Then I added another Compute Node to get the cardinality of the CurrencyRate as
| Code: |
SET OutputRoot = InputRoot;
SET OutputRoot.XML.CurrencyRates.CurrencyRate[1].Currency = 'INR';
|
8. Then I opened the Flow Debug Perspective and attached the flow engine where this message flow is running.
But in the Debug Flow, it doesn't show the change made in the value of Currency element.
Does it mean that even after changing the content descriptor, I cannot access the elements of the message in XML Domain??

| Code: |
SET OutputRoot = InputRoot;
SET OutputRoot.Properties.MessageFormat = 'XML';
|
From the above statement the Broker Assumes that the output domain is MRM.message type as XML.but you said you created a physical format XML1
| Code: |
SET OutputRoot = InputRoot;
SET OutputRoot.XML.CurrencyRates.CurrencyRate[1].Currency = 'INR';
|
If you going with predefined XML messages then the above statement should be like this
| Code: |
SET OutputRoot.MRM.CurrencyRates.CurrencyRate[1].Currency = 'INR';

Hi,
What I am actually trying to Achieve is that, convert CSV message into XML message and then process this message as XML domain and not as MRM domain.
| Code: |
SET OutputRoot.MRM.CurrencyRates.CurrencyRate[1].Currency = 'INR';
|
First of all, MRM domain will take CurrencyRates as the Root Element and You can refer to the elements inside CurrencyRates as OutputRoot.MRM.CurrencyRate[1].Currency
and NOT OutputRoot.MRM.CurrencyRates.CurrencyRate[1].Currency
Even if I use this code in my second Compute Node, it creates another <CurrencyRates><CurrencyRate><Currency>USD</Currency></CurrencyRate></CurrencyRates>
structure and appends it to the end of the message.
Nizzam,

Can you explain what do you mean by this quote?

| You said earlier that you created two physical formats 'TDS1' and 'XML1'. But that is not reflected it your ESQL which is setting the output message format to 'XML'. |
