The XSD schema that is used to validate the books.xml file.

Microsoft Visual Basic example code
This Visual Basic example code:

  • Creates an XMLSchemaCache object.

  • Adds the schema to the XMLSchemaCache object.

  • Creates a DOMDocument object and sets the schemas property to reference the books.xsd schema. The example code also sets the SelectionLanguage and SelectionNamespaces properties on the DOMDocument object.

  • Uses the XSD type-local-name function to select a node based on its data type.

  • Uses the XSD type-is function to return a node list that contains nodes only of the data type string.
