Package oracle.XML.parser.schema Description

The classes contained in package oracle.XML.parser.schema implement the Oracle XML Schema Processor for Java and support the World Wide Web Consortium (W3C) XML Schema specification.

XML Schema can be used to define a class of XML documents. The term instance document describes an XML document that conforms to a particular XML Schema definition or XSD. This document assumes familiarity with the W3C recommendations for XML Schema. The W3C recommendations can be found at http://www.w3.org/.

Features in Oracle XML Schema Processor for Java

The Oracle XML Schema Processor for Java is built on the Oracle XML Parser for Java v2 and includes these features:

• Built-In Data Types: XML Schema specifies a set of built-in datatypes. Some are defined and called primitive datatypes and they form the basis of the type system.
• Support for Simple API for XML (SAX) processing: streaming, constant memory usage, and linear processing time. SAX is an event-based API between an XML parser and an XML application. The object-based interface is supplied by the DOM.
• Fully supports the W3C.org XML Schema specifications of the candidate recommendation published October 24, 2000 and the final recommendation published May 2, 2001.

What's Needed to Run XML Schema Processor for Java

To run XML Schema Processor for Java, you need an operating system that supports Java 1.1.x or above and the JDK 1.1.x. or above.

Description of XSDBuilder

Builds an XMLSchema object from XMLSchema document. XMLSchema object is a set of objects (infoset) corresponding to top-level schema declarations and definitions. Schema document is 'XML' parsed and converted to a DOM tree. This schema DOM tree is 'Schema' parsed in a following order: (if any) builds a schema object and makes it visible. (if any) is replaced by corresponding DOM tree. Top-level declarations and definitions are registered as a current schema infoset of items. Finally, top-level tree elements (infoset items) are 'Schema' parsed. The resulting XMLSchema object is a set (infoset) of objects (top-level input elements). Object's contents is a tree with nodes corresponding to low-level element/group decls/refs preceded by node/object of type SNode containing cardinality info (min/maxOccurs).

XSDConstrainingFacet Class

---

Description of XSDConstrainingFacet

Implements XSDTypeConstants. XML Schema defines fifteen facets for applying constraints when deriving a datatype through restriction. Facets constrain the permitted values of a datatype.

Some facets use a value space for defining the restrictions on a datatype. A value space is the set of values for a given datatype. A lexical space is the set of valid literals for a datatype. Enumeration constrains the value space to a specified set of values. Each value in the value space of a datatype is denoted by one or more literals in its lexical space.
