Question

I have generated a set of classes using xsd.exe and created an XML document from the resulting generated code. I would now like to validate the serialized class instance against the original xsd.

My XML is like this:

<?xml version="1.0" encoding="UTF-8"?>
<MyRoot xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
   -- rest of XML document here
</MyRoot>

My XSD is like this:

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
   <xs:element name="MyRoot" type="MyRootType"/>
   -- MyRootType definition and rest of XSD
</xs:schema>

When I try to validate the XML using a XmlReader, I get the following error:
“The ‘MyRoot’ element is not declared.”

What could be wrong?

Answer 1

The approach was correct, but the XSD was not infact being read. I corrected this and it worked as expected.
