I've searched and read every thread I could find here about this, but I'm still confused.

I want to add namespace prefixes and namespace declarations to the Message and CrfActionGroup (and the CrfActionGroup's children) elements.

Code:

Please let me know what other details I should provide.

Thank you.

We are also getting confused,

in Which Language you required it
Java or ESQL

Both have been discussed a lot over here in this forum

What ESQL have you tried? What happened when you tried it? There's no point us suggesting things which have already failed to help you.

What about the docs & threads do you find confusing? What specific points are you hung up on?

I've already spent a ton of time reading namespace threads, just trying to see if any of them were trying to do the same thing I'm trying. THAT's my confusion, "Hmm... is this really the same thing?".

I've read where kimbert suggested to someone to walk the tree and add a namespace decl to each element. But before I do that, I wanted to try hard-coding just setting the ns decls on a couple elements.

Input message:

Code:

Code:

Code:

DECLARE msg NAMESPACE 'http://www.amica.com/amica_messaging';
SET OutputRoot.XMLNSC.Message.(XMLNSC.NamespaceDecl)xmlns:msg = msg;
SET OutputRoot.XMLNSC.Message.CrfActionGroup.(XMLNSC.NamespaceDecl)xmlns:msg = msg;

... which resulted in this message:

Code:

But I'm confused by the trace (or just not reading it right?):

Code:

(0x01000000):XMLNSC = ( ['xmlnsc' : 0xb2efd58]
(0x01000000):Message = (
(0x01000000):CrfActionGroup = (
(0x01000000):CommandReference = (
(0x03000100):refid = 'Command1' (CHARACTER)
)
(0x01000000):KeyGroup = (
(0x03000100):id = 'ID2004' (CHARACTER)
(0x03000100):keyGroupType = 'ServiceProvider' (CHARACTER)
(0x01000000):AlternateId = (
(0x03000100):state = 'exists' (CHARACTER)
(0x03000100):value = 'ab:234962' (CHARACTER)
(0x03000100):sourceLogicalId = 'AB' (CHARACTER)
)
(0x01000000):UUID =
)
(0x03000102)xmlns:msg = 'http://www.amica.com/amica_messaging' (CHARACTER)
)
(0x01000000):COMMAND = (
(0x01000000):CPRequest = (
(0x03000000):Command = '02' (CHARACTER)
(
(0x03000100):desc = 'AddPayment' (CHARACTER)
)
)
)
(0x03000102)xmlns:msg = 'http://www.amica.com/amica_messaging' (CHARACTER)
)
)
)

Am I on the right track? What am I missing? Did these 2 decl statements I coded actually put the namespace on these elements?

Thanks for your patience.

Sorry, there is no shortcut. Every individual node in the message tree must have the correct namespace assigned to it.

Or the document must have a default namespace, if that fits your needs.

Nope, that won't work. Unless you mean that the namespace of every node must be "" ( the empty string ).
Even if you use a default namespace ( xmlns="myNamespace" ) you still need to set the namespace of each and every child element to "myNamespace".

I wasn't implying a shortcut; I just want to make sure I'm setting the ns properly on a couple elements before writing a recursive loop.

Is what I've done so far correct?

I'm used to seeing traces that look more like this:

Code:

(0x01000010):XMLNS = ( ['xmlns' : 0x24b78be0]
(0x01000000)http://www.amica.com/amica_messaging:Message = (
(0x07000012)xmlns:msg = 'http://www.amica.com/amica_messaging' (CHARACTER)
(0x07000012)xmlns:loc = 'http://www.amica.com/Location' (CHARACTER)
(0x07000012)xmlns:impl = 'http://www.amica.com/Implementation' (CHARACTER)
(0x07000012)xmlns:pty = 'http://www.amica.com/Party' (CHARACTER)
(0x07000012)xmlns:ptyImpl = 'http://www.amica.com/PartyImpl' (CHARACTER)
(0x07000012)xmlns:adrImpl = 'http://www.amica.com/AddressImpl' (CHARACTER)
(0x07000012)xmlns:xsi = 'http://www.w3.org/2001/XMLSchema-instance' (CHARACTER)
(0x03000000):bodyType = 'Amica-XML' (CHARACTER)
(0x03000000):id = '2009-09-01-06.29.23.414211' (CHARACTER)
(0x03000000):authenticationId = 'A14122' (CHARACTER)
(0x03000000):timeStampCreated = '2009-09-01-06.29.22.' (CHARACTER)
(0x03000000):sourceLogicalId = 'HUB' (CHARACTER)
(0x03000000):destinationLogicalId = 'CMA' (CHARACTER)
(0x01000000)http://www.amica.com/amica_messaging:CrfActionGroup = (
(0x03000000):crfCmdMode = 'neverRespond' (CHARACTER)

(0x01000000)http://www.amica.com/amica_messaging:CommandReference = (

)
)

Ok, so I was told to provide more info on what I had tried/read so far. I did. Can someone please answer me now?

Compare and contrast these two pieces of your trace:

Quote:

(0x01000000)http://www.amica.com/amica_messaging:AlternateId = (

Quote:

(0x03000000):state = 'exists' (CHARACTER)

Notice the difference in how the elements are named. The first one has a NAMESPACE on it, the second one doesn't.

The second one is an attribute, not an element.

No. You need to re-read the examples in the docs.

Please tell us what you are puzzled about. We're not mind-readers!

You are not thinking about the problem correctly. First, get the message tree right. Make sure that your trace node output shows the correct namespace for each element. That is nothing to do with XMLNSC, by the way - it's basic message broker usage.

When you have a correct message tree, you can add one or more XMLNSC.NamespaceDecl attributes to create xmlns attributes in the output XML and control the namespace prefixes.

I'm sure trying to do that kimbert.

The code that produced the proper namespaced tree that I posted from a trace was:

Code:

DECLARE msg NAMESPACE 'http://www.amica.com/amica_messaging';
CREATE FIELD OutputRoot.XMLNS.msg:"Message";
DECLARE OutMsg REFERENCE TO OutputRoot.XMLNS.msg:"Message";
SET OutMsg.(XML.NamespaceDecl)xmlns:msg = 'http://www.amica.com/amica_messaging';

But the difference between that and what I'm trying to do is that it was transforming from MRM to XML and therefore creating the XML tree. In my current case, I just want to attach namespaces to the existing XML tree.
