Here is my XML

Answer 1

How to link an XSD to an XML document depends upon whether the XML document is using namespaces or not...

Without namespaces

Use xsi:noNamespaceSchemaLocation to provide a hint as to the XSD to be used:

• XML

  <root xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:noNamespaceSchemaLocation="example.xsd">
    <!-- ... -->
  </root>
  

• XSD

  <xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <xsd:element name="root">
      <!-- ... -->
    </xsd:element>
  </xsd:schema>
  

With namespaces

Use xsi:schemaLocation to provide a hint as to the XSD to be used:

• XML

  <ns:root xmlns:ns="http://example.com/ns"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
           xsi:schemaLocation="http://example.com/ns example-ns.xsd">
    <!-- ... -->
  </ns:root>
  

• XSD

  <xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
              targetNamespace="http://example.com/ns">
    <xsd:element name="root">
      <!-- ... -->
    </xsd:element>
  </xsd:schema>
