<< JDK (Java Development Kit) Tutorials

This chapter provides tutorial notes and example codes on DTD (Document Type Definition). Topics include writing an XML DTD validator using DOM and SAP interfaces; overriding error handler methods to print validation errors.

DOMValidator.java - XML DTD Validation with DOM

Testing DOM XML DTD Validator

SAXValidator.java - XML DTD Validation with SAX

Conclusion:

• JDK supports XML DTD validation through both DOM and SAX interfaces.
• It is very easy to override error handler methods to print XML validation errors with line numbers and detailed messages.

Notes and sample codes bellow are based on JDK/J2SDK 1.4.1_01.
