XML XSD Schema Validation
This section provides a tutorial example on how to write a XML schema validation program, XMLReaderValidator2.java, with JDK default XML parser.
Since JDK 1.5, you can use the built-in Xerces implementation to perform XML validation against XSD rules. Here is a simple XSD validation program, XMLReaderValidator2.java:
/* XMLReaderValidator2.java - Copyright (c) 2014, HerongYang.com, All Rights Reserved. */ import java.io.IOException; import org.xml.sax.XMLReader; import org.xml.sax.helpers.DefaultHandler; import org.xml.sax.helpers.XMLReaderFactory; import org.xml.sax.SAXException; import org.xml.sax.SAXParseException; class XMLReaderValidator2 { public static void main(String[] args) { String validationFeature = "http://xml.org/sax/features/validation"; String schemaFeature = "http://apache.org/xml/features/validation/schema"; try { String x = args[0]; XMLReader r = XMLReaderFactory.createXMLReader(); r.setFeature(validationFeature,true); r.setFeature(schemaFeature,true); r.setErrorHandler(new MyErrorHandler()); r.parse(x); } catch (SAXException e) { System.out.println(e.toString()); } catch (IOException e) { System.out.println(e.toString()); } } private static class MyErrorHandler extends DefaultHandler { public void warning(SAXParseException e) throws SAXException { System.out.println("Warning: "); printInfo(e); } public void error(SAXParseException e) throws SAXException { System.out.println("Error: "); printInfo(e); } public void fatalError(SAXParseException e) throws SAXException { System.out.println("Fattal error: "); printInfo(e); } private void printInfo(SAXParseException e) { System.out.println(" Public ID: "+e.getPublicId()); System.out.println(" System ID: "+e.getSystemId()); System.out.println(" Line number: "+e.getLineNumber()); System.out.println(" Column number: "+e.getColumnNumber()); System.out.println(" Message: "+e.getMessage()); } } }
