Validating xml using sax parser

30-Sep-2016 07:28

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.In case you want to make it explicit for reminding, it is fine, but it is not mandatory. The piece of XML to validate is specified in the constructor. 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. SAXParser [email protected] Error: Public ID: null System ID: file:/C:/herong/dictionary_invalid_Line number: 3 Column number: 49 Message: cvc-elt.1: Cannot find the declaration of element 'dictionary'.The application moves the cursor forward - 'pulling' the information from the parser as it needs.This is different from an event based API - such as SAX - which 'pushes' data to the application - requiring the application to maintain state between events as necessary to keep track of location within the document.

New features include experimental versions of DOM Level 2, SAX2 (beta 2), and parts of W3C Schema.

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.

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.

Alway get the following error msg while validating: Error planetclasses.xml:5:2: cvc-elt.1: Cannot find the declaration of element 'planetclasses'.
