Stax validating parser

On the other hand, for state-dependent processing, where the program needs to do one thing with the data under element A but something different with the data under element B, then a pull parser such as the Streaming API for XML (St AX) would be a better choice.With a pull parser, you get the next node, whatever it happens to be, at any point in the code that you ask for it.Interface Handling Content Events Document Events Element Events Character Events Handling Special Characters Setting up the Parser Setting up Error Handling Handling Non Fatal Errors Handling Warnings Running the SAX Parser Example without Validation To Run the Example without Validation Implementing SAX Validation Choosing the Parser Implementation Using the Validating Parser Ignorable White Space Configuring the Factory Validating with XML Schema Setting the SAX Parser Properties Associating a Document with a Schema Error Handling in the Validating Parser DTD Warnings Running the SAX Parser Examples with Validation Experimenting with DTD Validation Errors Experimenting with Schema Validation Errors Handling Lexical Events How the This chapter focuses on the Simple API for XML (SAX), an event-driven, serial-access mechanism for accessing XML documents.This protocol is frequently used by servlets and network-oriented programs that need to transmit and receive XML documents, because it is the fastest and least memory-intensive mechanism that is currently available for dealing with XML documents, other than the Streaming API for XML (St AX).

Pull parsers and the SAX API both act like a serial I/O stream.Both of these public void start Document() throws SAXException public void start Element(String namespace URI, String local Name, String q Name, Attributes atts) throws SAXException public void end Document() throws SAXException method defined in Setting Up I/O.You could start using your parser now, but it is safer to implement some error handling.In real-life applications, you will want to use the SAX parser to process XML data and do something useful with it.This section examines an example JAXP program, , are needed to provide hash tables and output.
