Serialization across 'like' attribute names

[MattL]

This serialization error appears to be not correct...

When a class defined in a specific namespace,e.g., "urn:A" and two
attributes which have the same local name, e.g., "Id", with one one attribute
defined as Qualified and in the namespace "urn:A" and the other attribute is
defined as Unqualified cannot be serialized.

The problem (as it appears to me) is that an unqualifed attribute does not
inherit a default namespace (per Namespaces in XML) and this is the error
thrown by the serializer, i.e., that both "Id" attributes appear in the same
namespace.

Thoughts!

To clarify myself:
The unqualified attribute SHOULD NOT inherit the default namespace and it
appears that the serializer "puts" it in the default namespace.

Hello MattL,

That is the default behaviour. If you done specify the namespace it resolves
to the default namespace.. am I missing something?

Hi Matt,

Please send me the schema you wish to make classes for.

Example

if this example the namespaces should be
{urn:A}Root
{""}Id
{urn:A}Id



[XmlRoot(Namespace="urn:A")]
[XmlType(Namespace="urn:A")]
public class Root
{
public class Root()
{
_xmlns.Add("x","urn:A");
}

private string _id;
private string _otherId;
private XmlSerializerNamespaces _xmlns = new XmlSerializerNamespaces();

[XmlNamespaceDeclarations()]
public XmlSerializerNamespaces Xmlns
{
get{return _xmlns;}
set{_xmlns = value;}
}
[XmlAttribute(Form=XmlSchemaForm.Unqualified)]
public string Id
{
get{return _id;}
set{_id = value;}
}

[XmlAttribute("Id", Namespace="urn:A", Form=XmlSchemaForm.Qualified)]
public string OtherId
{
get{return _otherId;}
set{_otherId = value;}
}
}

Hi Matt,
I think you are saying (ignoring your implementation) that you want to get
the following XML:

<Root xmlns="urn:A">
<id>namespaced value</id>
<id xmlns="">non-namespaced value</id>
</Root>

Is this correct? From a schema perspective, this is nearly impossible to
describe, so best practice would seem to dicate not doing this. However,
since it is to a degree, just a matter of what you can serialize, I think
it's possible to make this happen.

If so, try this:

[XmlRoot("urn:A")]
public class Root
{
[XmlElement(ElementName="id", Namespace="urn:A", DataType="string")]
public string firstId;

[XmlElement(ElementName="id", Form=XmlSchemaForm.Unqualified,
DataType="string")]
public string secondId;

public Root()
{
firstId = "namespaced value";
secondId = "non-namespaced value";
}
}

Hope this helps,

Dan,

I apoligize, I should have been using [XmlAttribute] and not [XmlElement]

consider this XML

<x:root xmlns:x="urn:A">
<x:child Id="1" x:Id="2"/>
</x:root>

Now...two Ids exist. One is qualified as {""}Id and the other {urn:A}Id
The default namespace is xmlns="" not "urn:A". When you attempt to
serialize this you get a namespace collision in that the serializer believes
that {""}Id and {urn:A}Id belong to the same namespace, i.e., urn:A.

Sorry for the confusion.

Hi Matt,

Yes, you're going to have lots of serialization issues if you try to do
this. Since the nill namespace is not addressible, and because the rules
of XML say that unqualified child attributes default to the namespace of
their parent element, it's at least debatable as to whether this particular
construct can even be described using a schema.

As a "did you try this" - I'd be shocked if it worked - but did you try
treating the nill namespace value "" as a string, and making it a qualified
attribute?

[MattL]

Hi Dan,
[1] and [2] (I think) state that the unprefixed attribute *does not* inherit
the namespace of the parent element rather it inherits the default namespace
which is empty string. I believe that [2] also states that the {""}Id and
{"someUri"}Id are unique since they are uniquely qualified.

So, either I'm mistaken in my interpretation of this or the serializer
simply cannot perform this operation (which I think indicates a bug).

[1] [url]http://www.w3.org/TR/REC-xml-names/#defaulting[/url]
[2] [url]http://www.w3.org/TR/REC-xml-names/#uniqAttrs[/url]

Thoughts?

Thx,

-MattL
