Hi,
Why when I mapped MRM to XML using the Mapping node the XML message data does not have the xml declaration? I din check the "Suppress XML Declaration" check box in the message set Physical properties. Or do I need to add in using compute node? Thanks |

How you determine that XML message does not have XML declaration?
There is no declaration after you place output message to a queue? |

The 'Suppress XML Declaration' option only applies to the MRM domain - it's an MRM XML physical format property. The output from your Mapping node is in XML domain, and there is currently no facility to add an XML declaration in the mapper.
So you will need to add the XML declaration yourself prior to output, using a Compute node. |

Hi,
Oh ok thanks. that is what I did now. Tot there maybe a better way. but why when i code
OutputRoot.XML.Exception.a = 'a';
OutputRoot.XML.Exception.b = 'b';
the XML declaration is automatically generated.
Cheers. |

Use the MRM domain and the message set namespace or use the XMLNS domain and make sure to use the namespace declarations:
DECLARE myns NAMESPACE 'urn:mycompany.com/ns/myns';
SET myref.myns:myfield='myfieldvaluehere';
Enjoy

angka: I think you mean 'XML namespace declaration' not 'XML declaration'.
An XML declaration always occurs at the start of the document ( if at all ), and looks like this:
<?xml version="1.0"?>
An XML namespace declaration can occur once on any element. It defines a namespace prefix and looks like this:
<element1 xmlns:prefix1="http://mynamespace" prefix1:myAttr="myValue">
Now that you understand that, you should be aware that
- The MRM XML message set property 'Suppress XML Declaration' has nothing to do with your problem.
- The MRM XML message set properties contains a table which allows you to define one 'preferred prefix' for each namespace in your output document.
- The XML/XMLNS/XMLNSC domains handle namespace declarations in a completely different way. The docs contain plenty of examples. |

| one more thing: if you want to be a good citizen, you should edit the title of this thread to 'XML namespace declarations' |

Hi,
I defined the prefix and namespace in the message set properties table but the output of the XML message did not include the namespace.
I am using the mapping node mapping from physical format CWF (parse to MRM) to output XML. |

Not enough information to diagnose the problem.
- Post a trace of the message tree just before the output node.
- Tell us what output message you were expecting
- Tell us what output message you got. |

Usually if you have imported something like a copybook (CWF) you cannot just parse it and output it with namespaces in xml.
You would have to map it first to a namespace aware message set.
Enjoy

Hi,
Sorry for the vague description. Below is what i wanna achieve
When my message flow pick up from local queue the messge data is in CWF format. Then in my compute node i parse it to MRM domain and then it go thru a mapping node. the output message from the mapping node uses message set using XMLNS domain . it den go into another compute node. i set the xml declaration and namespace here. below are my code.
SET OutputRoot.XMLNS.(XML.XmlDecl).(XML.Version) = '1.0';
SET OutputRoot.XMLNS.IncidentEvent.(XML.NamespaceDecl).Xmlns:xsi = ' http://www.w3.org/2001/XMLSchema-instance';
SET OutputRoot.XMLNS.IncidentEvent.(XML.NamespaceDecl).Xmlns:xsd = ' http://www.w3.org/2001/XMLSchema';
I got the following error when it try to put to a MQOutput node.
"Element must have a namespace specified if there is a default namespace in scope"
Is the error due to i setting 2 namespaces? but if so then how can i set 2 namespaces in one element?
btw am i right to say that the properties in the message set for namespace and XML declarations are for MRM domain??
Thanks.. |

Your message tree is incorrect. Somewhere in the message tree you have defined a default namespace (see comment at the end of this post). Somewhere else in that message tree there is an element in noTargetNamespace. The XML serialization logic cannot possibly output anything sensible, so it throws this error.

No, it is not. But you are not setting namespaces. You are declaring prefixes for namespaces. You can declare 100 prefixes for 100 different namespaces on the same element if you really want to.

That is correct.
Not sure whether you posted the correct code, but you should be using 'xmlns' not 'Xmlns'. I would change that and re-test before trying anything else. |

Hi,
Sorry, i type wrongly i am using 'xmlns' =)
and i didnt include one of the line...
SET OutputRoot.XMLNS.IncidentEvent.(XML.NamespaceDecl).xmlns:xsi = ' http://www.w3.org/2001/XMLSchema-instance';
SET OutputRoot.XMLNS.IncidentEvent.(XML.NamespaceDecl).xmlns:xsd = ' http://www.w3.org/2001/XMLSchema';
SET OutputRoot.XMLNS.IncidentEvent.(XML.NamespaceDecl).xmlns = 'http://tempuri.org/XSDSchema.xsd';
what should I do to include xmlns = 'http://tempuri.org/XSDSchema.xsd' to the element? thanks |
