Guys,
I am running the following configuration on Windows(XP) :
Message Broker Toolkit: 6.0.2, Interim Fix 8
Message Broker: MQSI 6.0.0.5
I have an HTTP Input Node, configured to use the XMLNSC Parser that accepts the following message:
| Code: |
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:rbac="http://contracts.it.nednet.co.za/services/common-services/2008-06-14/RBAC">
<soapenv:Header>
<context:EnterpriseContext xmlns:context="http://contracts.it.nednet.co.za/Infrastructure/2006-11-01/EnterpriseContext">
<context:ExecutionContextID>14809BCF-88A2-BBB2-E066-96B90AAF9EF1</context:ExecutionContextID>
<context:SourceInfo>
<context:ChannelID>0</context:ChannelID>
</context:SourceInfo>
<context:SecurityInfo>
<context:Ticket>
<context:Identity>5066551195</context:Identity>
<context:AuthenticationLOC>0</context:AuthenticationLOC>
<context:SessionSequenceNr>1215</context:SessionSequenceNr>
<context:ExpiryDateTime>2007-11-22T22:30:32.994Z</context:ExpiryDateTime>
<context:IdentifierType>PSI</context:IdentifierType>
<context:TicketSignature>5FA4DEB27381EA3C584F3B3B0763255DBCF9676C</context:TicketSignature>
</context:Ticket>
</context:SecurityInfo>
<context:InstrumentationInfo>
<context:InstrumentationContextID>ECF2B338-6742-7423-E42F-0EC51F31F6AE</context:InstrumentationContextID>
</context:InstrumentationInfo>
</context:EnterpriseContext>
</soapenv:Header>
<soapenv:Body>
<rbac:RBACOperationAddRq>
<rbac:Operation>
<rbac:BusinessObjectName>RBAC</rbac:BusinessObjectName>
<rbac:OperationName>RBAC2</rbac:OperationName>
</rbac:Operation>
<rbac:Validation>RBAC3</rbac:Validation>
</rbac:RBACOperationAddRq>
</soapenv:Body>
</soapenv:Envelope>
|
In my Compute Node, I want to extract the values from the incoming header, i.e. 'ExecutionContextID' and 'Identity', etc. and build it into a Cobol output message. But for now I'm just battling to get the values extracted - so I get 'Nothing' returned from the following Procedure:
| Code: |
CREATE PROCEDURE GetValues() BEGIN
SET OutputRoot.XML.MyMsg.MyData1 = COALESCE(InputRoot.XMLNSC.Envelope.Header.EnterpriseContext.ExecutionContextID,'Nothing');
SET OutputRoot.XML.MyMsg.MyData2 = COALESCE(InputRoot.XMLNSC.Envelope.Header.EnterpriseContext.SecurityInfo.Ticket.Identity,'Nothing');
END
|
...So how do I get to the values of my tags? I suppose it has something to do with the namespaces.
Thanks in advance |

Please don't use the XML Domain.
Even on output.
Yes, your problem is that you aren't using namespaces to address the elements in your input tree.

Something....it has everything to do with your namespaces 
Search the forum for DECLARE NAMESPACE...you should find relevant snippets of code.
Regards. |

Thanks guys, I did some reading and searching and consulting and I got to my answer - Elvis, thanks, I see you're right - it is all about declaring Namespaces ...
Jeff, the reason for using the XML domain as input is to pick up the Root element tag to use in a CASE statement:
Quote from Kimbert:
| Quote: |
| You cannot access the name of the root tag from ESQL if you are using the MRM domain for your XML messages. I suggest that you change your flow to use the XMLNSC domain. Or at least the XMLNS domain. |
My XML OutputRoot is just used to test for now. Ultimately I want to map these values to a COBOL structure.
I want to thank you guys for a brilliant forum - it helps a lot!

You can get at the root tag just as easily from the XMLNSC parser as the XML Parser.
