Java sax parser validating

But the example Java program can still run using JDK 1.6 and Xerces2 2.9.1 Xerces-J package can also be loaded by the SAXParser Instance() method. Here is my /** * * Copyright (c) 2002 by Dr. Application output will look like below snap: package com.g2. XML validation is the cornerstone of good document authoring.In XML parsers, validation is usually turned off by default because many XML authors are not writing constraints; leaving it off helps to avoid lengthy processing in production environments.To turn on validation, you must request it explicitly.Two things must be understood about the validating parser: method on white space that it knows to be irrelevant.From the standpoint of an application that is interested in processing only the XML data, that is a good thing because the application is never bothered with white space that exists purely to make the XML file readable.

An XMLSchema object represents the DOM structure of an XML schema document and is created with an XSDBuilder class object.

In other words, it can tell you whether the document is valid.

If validation is not activated, however, it can only tell whether or not the document is well-formed, as was shown in the previous section when you deleted the closing tag from an XML element.

SAXParser is recommended if SAX parsing event notification is required in addition to validation with a schema.

DOMParser is recommended if the DOM tree structure of an XML document is required for random access and modification of the XML document.

uses the non-validating parser by default, but it can also activate validation.
