XML Validation Problems

[tlwright1414]

I am not getting expected validation errors when attributes in my xml
are not defined in my schema. Does anyone know if this is normal
behavior? I am however getting the expected validation errors for
things like 'invalid child element', etc...

here's is my code...

XmlSchemaCollection schemaCol = new XmlSchemaCollection();
schemaCol.Add(schemaNamespace, schemaUri);

XmlValidatingReader vr = new XmlValidatingReader(xml,
XmlNodeType.Document, null);
vr.ValidationType = ValidationType.Schema;

if(schemaCol != null)
{
vr.Schemas.Add(schemaCol);
}

vr.ValidationEventHandler += new
ValidationEventHandler(ValidationCallBack);

while(vr.Read())
{
}
vr.Close();

T.L.,

The first things I would check is whether attributeFormDefault on the
<xs:schema> element is set to "qualified," and your targetNamespace
URI matches the namespace URI you're applying to attributes in the
instance document.

By default, attributes will be unqualified by a namespace URI unless
you expressly qualify them with a prefix, so those encountered in the
instance document may not be in your targetNamespace URI after
all, and that would explain why they would not be getting validated.

Please include a snippet of the XML Schema and XML instance
document you're trying to validate if this doesn't help, and someone
here can probably give a more concrete explanation based on what
you're using.
