XSD schema for the above XML document, address.xsd, can be given as follows: The Validation Event Handler event is used to define an event handler for receiving the notification about XSD schema validation errors.The validation errors and warnings are reported through the Validation Event Handler call-back function.Oracle XML DB is a set of Oracle Database technologies related to high-performance handling of XML data: storing, generating, accessing, searching, validating, transforming, evolving, and indexing.
This duality means that the same data can be exposed as rows in a table and manipulated using SQL or exposed as nodes in an XML document and manipulated using XQuery, the DOM, or XSL transformation.
Access and processing techniques are independent of the underlying storage method.
Using views, you must first register an XML schema with annotations that represent a bidirectional mapping between XML Schema data types and either SQL data types or binary XML encoding types.
You can then create an Oracle XML DB provides high performance and scalability for XML operations, letting you manage the storage and retrieval of complex, large, or many XML documents.
For example, consider the following XML document: XSD schema defines elements, attributes, and the relationship between them.
