				This example installs an error handler to a parser. The error handler logs error messages to a logger (see e385 The Quintessential Logging Program). 
				    // Create a builder
				    DocumentBuilder builder = DocumentBuilderFactory.newInstance().newDocumentBuilder();
				    
				    // Set an error listener
				    builder.setErrorHandler(new MyErrorHandler());
				    
				    // Use the builder to parse the file
				    Document doc = builder.parse(new File("infilename.xml"));
				    } catch (SAXException e) {
				        // A parsing error occurred; the xml input is not valid.
				        // This exception can still be thrown, even if an error handler is installed.
				    } catch (ParserConfigurationException e) {
				    } catch (IOException e) {
				    }
				    
				    // This error handler uses a Logger to log error messages
				    class MyErrorHandler implements ErrorHandler {
				        //  This method is called in the event of a recoverable error
				        public void error(SAXParseException e) {
				            log(Level.SEVERE, "Error", e);
				        }
				    
				        //  This method is called in the event of a non-recoverable error
				        public void fatalError(SAXParseException e) {
				            log(Level.SEVERE, "Fatal Error", e);
				        }
				    
				        //  This method is called in the event of a warning
				        public void warning(SAXParseException e) {
				            log(Level.WARNING, "Warning", e);
				        }
				    
				        // Get logger to log errors
				        private Logger logger = Logger.getLogger("com.mycompany");
				    
				        // Dump a log record to a logger
				        private void log(Level level, String message, SAXParseException e) {
				            // Get details
				            int line = e.getLineNumber();
				            int col = e.getColumnNumber();
				            String publicId = e.getPublicId();
				            String systemId = e.getSystemId();
				    
				            // Append details to message
				            message = message + ": " + e.getMessage() + ": line="
				                + line + ", col=" + col + ", PUBLIC="
				                + publicId + ", SYSTEM=" + systemId;
				    
				            // Log the message
				            logger.log(level, message);
				        }
				    }
				
				Given the following input file, MyErrorHandler.fatalError() is called and parse() throws a SAXParseException as well.
