I have an XMl file that looks like:\[code\]<?xml version="1.0" encoding="UTF-8"?><game > <moves> <turn>2</turn> <piece nr="1" /> <turn>4</turn> <piece nr="1" /> </moves></game>\[/code\]I am writing a Java program that takes the XML file as input then parses it with SAX and SAX filter and computes:
iece-count>2</siece-count></s:statistics>\[/code\]The prefix \[code\]s\[/code\] is a reference to a namespace.My program so far is:\[code\] public class test{ public static void main(String[] args) throws Exception { if (args.length != 2) { System.err.println("error "); System.exit(1); } String xmlInput = args[0]; String filteredXML = args[1]; test test1 = new test(); test1.sax(xmlInput, filteredXML); } private void sax(String gameXML, String filteredGameXML)throws Exception{ FileInputStream fis = new FileInputStream( gameXML); InputSource is = new InputSource(fis); XMLReader xr = XMLReaderFactory.createXMLReader(); XMLFilter xf = new MyFilter(); xf.setParent(xr); xr = xf; xr.parse(is); xr.setFeature("http://xml.org/sax/features/namespaces", true); DefaultHandler handler = new DefaultHandler(); xr.setContentHandler(handler); } private class MyFilter extends XMLFilterImpl{ StringBuffer buffer; int temp=0; int sum=0; String ff; int numof=0; private MyFilter() {} @Override public void startDocument() throws SAXException { System.out.println( "START DOCUMENT" ); numof=0; } public void startElement(String namespaceURI, String localName, String name, Attributes attributes) throws SAXException{ if(localName.equals("turn")){ buffer=new StringBuffer(); } if("piece".equals(name)){ numof++; } } public void characters(char[] ch, int start, int length) throws SAXException { String s=new String(ch, start, length); if(buffer!=null){ buffer.append(s); } } public void endElement(String uri, String localName, String name)throws SAXException { if(buffer!=null ){ ff=buffer.toString(); temp=Integer.valueOf(ff); sum=sum+temp; } buffer=null; } public void endDocument() throws SAXException { System.out.println( "END DOCUMENT" ); System.out.println("sum of turn: "+ sum); System.out.println("sum of piece: "+ numof); } } }\[/code\]What should I do next?
- the sum of the content of turn element (here=6)
- the number of piece elements (here=2)
