Validating xml using sax parser
This may involve storing the data into a database or writing it out to a stream.
During parsing, the parser may need to access external documents.
Notice that the default SAXParser in JDK 1.7 is the "xerces" implementation.
Running with JDK 1.7 and Xerces2 2.11.0 in 2013: c:\Progra~1\Java\jdk1.7.0_07\bin\javac XMLReader c:\Progra~1\Java\jdk1.7.0_07\bin\java SAXValidator dictionary_invalid_org.apache.xerces.

Basically XML parsers are of two types : Many parsers are available, including Alpha Works XML for Java, which is used by IBM, Microsoft XML Parser, which is used in Microsoft Internet Explorer, and a parser called expat, which is used in the Netscape Navigator 6 browser application.
Various Validating Parsers are Version 1 of IBM's XML Parser for Java was the highest rated Java XML parser in Java Report's February 1999 review of XML parsers.
Any compliant implementation must support the W3C XML Schema language, but other languages like RELAX NG or Schematron may be supported as well.
XML Schema (XSD) Validation using SAXParser This section describes a tutorial example on how to the Xerces2 SAXParser class to validate an XML document assigned with an XSD file.
The XML parsed, makes it possible for an XML application, such as a formatting engine or a viewer, to access the structure and content of an XML document.Note that tutorial examples given in this section were taken in 2002 using JDK 1.4 and Xerces-J 2.3. 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. XML4J 3.0.1 is based on the Apache Xerces XML Parser Version 1.0.3.New features include experimental versions of DOM Level 2, SAX2 (beta 2), and parts of W3C Schema.
