Cannot resolve the name 'xmldsig:Signature' to a(n) 'element

[ivanpgs]

Hi all,

Lately I have been going through differents problems while trying to validate a XML along with a XSD schema.

The message in the subjetc: Cannot resolve the name 'xmldsig:Signature' to a(n) 'element, is produced by the next code:

And if I change the import line at the MAIN XSD file from this:
<xs:import namespace="http://www.w3.org/2000/09/xmldsig#"/>
...to this
<xs:import namespace="http://www.w3.org/2000/09/xmldsig#
http://www.w3.org/TR/2002/REC-xmldsig-c ... schema.xsd"/>

then I get this another error message:

src-resolve.4.2: Error resolving component 'xmldsig:Signature'. It was detected that 'xmldsig:Signature' is in namespace 'http://www.w3.org/2000/09/xmldsig#', but components from this namespace are not referenceable from schema document 'file:///C:/Ivan/Programas/eclipse/workspace/TratamientoXML/xsd/PeticionPagosFirma.xsd'. If this is the incorrect namespace, perhaps the prefix of 'xmldsig:Signature' needs to be changed. If this is the correct namespace, then an appropriate 'import' tag should be added to 'file:///C:/Ivan/Programas/eclipse/workspace/TratamientoXML/xsd/PeticionPagosFirma.xsd'.

It seems that the first error is because it does not find the Signature element, but when you provide it with the xsd then it said that it cannot be referenced from the MAIN XSD file.

Im using the last Xerces libraries and I just cannot get any idea to solve it.

Anyone can help me?

Thanks in advance.

Hi,

First of all the xml file should point to the main xsd schema like this:

Code: Select all

<PeticionFirmada xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

 xsi:noNamespaceSchemaLocation="path/to/schema/main.xsd">

So the attribute xsi:noNamespaceSchemaLocation is added and points to the main schema.

Second of all the

Code: Select all

<xs:import namespace="http://www.w3.org/2000/09/xmldsig#

http://www.w3.org/TR/2002/REC-xmldsig-core-20020212/xmldsig-core-schema.xsd"/>

you are using to import the signatures schema on the web should go to this:

Code: Select all

<xs:import namespace="http://www.w3.org/2000/09/xmldsig#"         schemaLocation="http://www.w3.org/TR/2002/REC-xmldsig-core-20020212/xmldsig-core-schema.xsd"/>

So a schema location attribute is added to point to the shema on the web.

After that there will be errors reported in the XML file but only because it contains values which do not have the correct facets as described in the schema.

Hope this helps,
Regards, Radu.

Thanx for your answer but I am afraid that it does not the trick...

I do not why it stills does not recognize the schemaLocation or something like that, maybe it is a kind of bug regarding Xerces libraries...

The point is that even when I point to the schemaLocation It appears the same message (in red).

The others are just the errors having to do with facets and restrictions and those are allright.

An then the last in green are just messages relating the signature validation, which is okay too.

Thank you for your post and I will keep on searching a solution.

Hi Ivan

The error you are receiving signifies that the signatures schema is not referred correctly in the import statement.
By the way, I notice that you are not using Oxygen for validation (the errors Oxygen gives for validation do not have the format that you are describing).
If you are running Oxygen as an Eclipse plugin maybe you should right click the XML file, go to Open With and choose Oxygen XML Editor.
Maybe the validator you are using cannot import remote schemas.
You could save the signatures schema on your disk in the same folder with the main schema file and refer to it locally in the <import> statement from the main schema like:

Code: Select all

<xs:import namespace="http://www.w3.org/2000/09/xmldsig#"         schemaLocation="xmldsig-core-schema.xsd"/>

Regards, Radu.

[ivanpgs]

Yeah, I already did it too,

In fact, when I began it was a local file, just downloaded from the w3c web and put it in the hard-disk and treated as file:///path/to/schema/xmldsig-core-schema.xsd.
The same error is raised.

And you are rigth, I am not using Oxygen, I am only using Eclipse without the Oxygen plug-in. Maybe I should try Oxygen and try to see if the errors go away.

I'd try and tell you.

Thanks for your help.
