Xml Parsing

Hi Java Lovers

I have just started SAX Parsing in Java.

Now I wanna parse the particular group(like admin,contact etc) and get the passcount of that particulatr group only .For example if I a want admin details

I shoud get the following output

Please help me with it.

What do you have so far? Can you detect when a <Date> Element occurs?

I was using below code

import javax.xml.parsers.SAXParser;
	import javax.xml.parsers.SAXParserFactory;
	 
	import org.xml.sax.Attributes;
	import org.xml.sax.SAXException;
	import org.xml.sax.helpers.DefaultHandler;
	 
	public class XmlParser {
	 
	 public static void main(String argv[]) {
		 
		  
	 
	  try {
	 
	     SAXParserFactory factory = SAXParserFactory.newInstance();
	     SAXParser saxParser = factory.newSAXParser();
	 
	     DefaultHandler handler = new DefaultHandler() {
	 
	     boolean bidentifier = false;
	     boolean bfname = false;
	     boolean blname = false;
	     
	 
	     public void startElement(String uri, String localName,
	        String qName, Attributes attributes)
	        throws SAXException {
	    	 String s = "admin";
	        //System.out.println("Start Element :" + qName);
	        if(qName.equals(s)){
	        	System.out.println(qName);
	        	bidentifier = true;
	        }
	        	
	        if (qName.equalsIgnoreCase("Date")) {
	           bfname = true;
	        }
	 
	        if (qName.equalsIgnoreCase("PassCount")) {
	           blname = true;
	        }
	        
	 
	       
	 
	     }
	 
	     public void endElement(String uri, String localName,
	          String qName)
	          throws SAXException {
	 
	        // System.out.println("End Element :" + qName);
	 
	     }
	 
	     public void characters(char ch[], int start, int length)
	         throws SAXException {
	    	
	          
	         if (bfname) {
	        	 if(bidentifier){
	            System.out.println("Date :---> "
	                + new String(ch, start, length));
	            bfname = false;
	        	 }
	          }
	 
	        if (blname) {
	        	if(bidentifier){
	              System.out.println("Passcount :---> " +  new String(ch, start, length));
	                 
	              blname = false;
	              bidentifier = false;
	        	}
	              
	           }

}
	 
	      };
	 
	      saxParser.parse("d:/EnhancedReporting/GroupsHistoricalData.xml", handler);
	 
	    } catch (Exception e) {
	      e.printStackTrace();
	    }
	  }
	 
	}

It gives me the following output

admin
Date :--->

Passcount :--->

admin
Date :--->

Passcount :--->

Try not setting bfname or the other flags to false until the matching endElement() is called.

Note that the characters () method may be called multiple times inside a given Text node.

This is how it should be modified (overlapping what have been advised).

[1] If you want to use String s uniformly and generally in the handler, move the declaration outside of the startElement handling.

[2] In the same spirit of electing the flags in the startElement() because the detection in all cases of interested is on the element's name, you should take down the flags in the endElement().

[3] Flags shouldn't be switched in the characters handling.
