Schema validation with a SAX parser

In this section we shall validate the example XML document catalog.xml with XML schema document catalog.xsd, with the SAXParser class. Import the oracle.xml.parser.schema and oracle.xml.parser.v2 packages.

Creating a SAX parser

Create a SAXParser object and set the validation mode of the SAXParser object to SCHEMA_VALIDATION, as shown in the following listing:

SAXParser saxParser=new SAXParser(); saxParser.setValidationMode(XMLParser.SCHEMA_VALIDATION);

The different validation modes that may be set on a SAXParser are discussed in the following table; but we only need the SCHEMA-based validation modes:

Validation Mode	Description
NONVALIDATING	The parser does not validate the XML document.
PARTIAL_VALIDATION	The parser validates the complete or a partial XML document with a DTD or an XML schema if specified.
DTD_VALIDATION	The parser validates the XML document with a DTD if any.
