XmlSchema Validation Error

[Igor Koretsky]

Hi.

Using VB.Net System.Xml 1.0
SchemaCollection Object

I am getting an error when trying to add
‘Schema A’ to the SchemaCollection.

Here are my schema files..

Schema A ‘Includes’ Schema B.

The error is..

restriction

I can validate this schema in Stylus that is using Xerces Validation Parcer.
What can I do to skip/fix this error?

Thank You.

Schema B does not have a targetNamespace and including this in Schema A
causes a chameleon include. (Include of a schema without a targetNamespace)
XmlSchemaCollection does not support chameleon includes. If you provide a
targetNamespace for schema B and make it to be the default namespace in
schema B, it should fix the error.

Thanks,
Priya

Priya,

Thank you for your response.
Now I see where the problem is.

Unfortunately I can’t change the schema that supplied by another company.
I am developing software (Win Forms VB.NET) that receives and processes XML
documents.
The very first step I have to do is validate incoming files against schema
and show errors if XML file did not pass the validation.
Can you suggest what approach/tool I should be using to make it work?

Thank You.

This problem is fixed by the XmlSchemaSet class (Replacement for
XmlSchemaCollection) in .Net 2.0. Can you move to .NET 2.0?

Otherwise, the only workaround is for you to clone the included schema
yourself and set all qualified names to the right targetNamespace.
ie. all properties on the SOM of type XmlQualifiedName like BaseTypeName,
RefName, SchemaTypeName, ItemTypeName etc

Thanks,
Priya

Thanks Priya,
You covered my question.
To bad they are not going to fix it for .NET 1.1
