Getting Error Attribute xsi:noNamespaceschemaLocation is not allowed

Question

I am getting this error:

Error:(7, 50) cvc-complex-type.3.2.2: Attribute 'xsi:noNamespaceschemaLocation' is not allowed to appear in element 'fieldsMapper'.

My XML file is below:

<?xml version="1.0"?>
<fieldsMapper xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
              xmlns="https://www.company.com/core"

                just groovy code

        </field>
    </fields>
</fieldsMapper>

My fieldsMapper.xsd is as below:

<?xml version="1.0" encoding="UTF-8"?>

    <xs:attribute type="xs:string" name="sourceType"/>
    <xs:attribute type="xs:string" name="id"/>
  </xs:complexType>
</xs:schema>

Any idea why I am getting this error? The XML file is valid and so is the XSD file. I tried changing the elementFormDefault to unqualified instead of qualified but it did not make any difference.

For starters,

xsi:noNamespaceschemaLocation

should be

xsi:noNamespaceSchemaLocation
               ^

...but you shouldn't even be using xsi:noNamespaceSchemaLocation since your XML is in a namespace. Use xsi:schemaLocation instead.

Change

xsi:noNamespaceschemaLocation="http://www.company.com/core/fieldsMapper 
                               fieldsMapper.xsd"

to

xsi:schemaLocation="http://www.company.com/core fieldsMapper.xsd"

Note both xsi:schemaLocation and the change of the namespace to match your XML's default namespace and the targetNamespace of the XSD.
