UBLExtension in InvoiceType with incorrect namespace prefix about ph-ubl

[phax]

You mean the difference between "cec" and "ext"?
This makes no difference since this "namespace prefix" is only relevant for the "persisted representation" of the XML. When read into memory, both "ext" and "cec" are expanded to "urn:oasis:names:specification:ubl:schema:xsd:CommonExtensionComponents-2" and therefore the DOM trees in memory are identical.

Yeah in memory is using the same namespace, no problem there, but I was wondering why the "persisted representation" (if I understand correctly you mean when the DOM is saved to a XML, the same I tried to say - sorry my english is not too good) it generates the namespace only for this element UBLExtension and doesnt use the namespace already defined with ext in the Invoice node parent, this is what I was expecting ..

<Invoice xmlns:cac="urn:oasis:names:specification:ubl:schema:xsd:CommonAggregateComponents-2" 
xmlns:cbc="urn:oasis:names:specification:ubl:schema:xsd:CommonBasicComponents-2" 
xmlns:ccts="urn:un:unece:uncefact:documentation:2"
xmlns:ds="http://www.w3.org/2000/09/xmldsig#"
xmlns:ext="urn:oasis:names:specification:ubl:schema:xsd:CommonExtensionComponents-2"
....
<ext:UBLExtensions>
<ext:UBLExtension>

but I received :

<Invoice xmlns:cac="urn:oasis:names:specification:ubl:schema:xsd:CommonAggregateComponents-2" 
xmlns:cbc="urn:oasis:names:specification:ubl:schema:xsd:CommonBasicComponents-2" 
xmlns:ccts="urn:un:unece:uncefact:documentation:2"
xmlns:ds="http://www.w3.org/2000/09/xmldsig#"
xmlns:ext="urn:oasis:names:specification:ubl:schema:xsd:CommonExtensionComponents-2"
....
<cec:UBLExtensions xmlns:cec="urn:oasis:names:specification:ubl:schema:xsd:CommonExtensionComponents-2">
<cec:UBLExtension>

The problem is, that the namespace prefixes are lost when reading the DOM. By default UBL20NamespacePrefixMapper.getInstance() is used to provide the namespace prefixes when marshalling (writing) the document back to XML. Would it be okay for you, to provide your own marshaller, so that you can replace "cec" with "ext" or do you want exactly the same prefixes as when the document was read?

Any news from your side?

Hi, I had to change the namespaces manually to what the other endpoint was expecting .

[phax]

So what shall we do?
Close this issue?
Or provide a custom namespace-prefix-mapper?

Hi Mr. Philip

How I can replace "cec" with "ext"?
