How to read a cdata using sax parser

I am new to XML & i want to read a query from xml.
which will be in cdata tag.
please help me by providing source code for reading cdata usin sax parser.
thanx in advance

You can use the following snippet- the characters() method would catch any CDATA sections within XML:

package com.saxparser;
 
 
import java.io.ByteArrayInputStream;
 
import javax.xml.parsers.SAXParser;
import javax.xml.parsers.SAXParserFactory;
 
import org.xml.sax.Attributes;
import org.xml.sax.InputSource;
import org.xml.sax.SAXException;
import org.xml.sax.helpers.DefaultHandler;
import org.xml.sax.helpers.ParserAdapter;
 
public class ServerSideSAXParser extends DefaultHandler {
private static String START_TAG= "start";

public synchronized void  startElement(String namespace, 
String localName, 
String qName,
Attributes atts) {
if (localName.equals(START_TAG)) 
{
System.out.println(START_TAG+" encountered");

}
}
public synchronized void characters(char[] cbuf, int start, int len) 
   {
  System.out.print("Characters:");
  System.out.println(new String(cbuf,start,len));
   }
public synchronized void processingInstruction(String target, String data) 
  throws SAXException 
   {
  System.out.println("ProcessingInstruction:"+target+" "+data);
   }

public synchronized void parseString(String msgXML) throws Exception 
{

System.out.println("Processing Message " + 
 msgXML);
     SAXParserFactory spf = 
 SAXParserFactory.newInstance();
   SAXParser sp = spf.newSAXParser();
   System.out.println("CLASS :"+sp.getClass());
   System.out.println(System.getProperty("javax.xml.parsers.SAXParserFactory"));
   ParserAdapter pa = 
 new ParserAdapter(sp.getParser());
   pa.setContentHandler(this);
byte bytearray[] = msgXML.getBytes();
ByteArrayInputStream bais = new ByteArrayInputStream(bytearray);
   pa.parse(new InputSource(bais));
   
   
 
}
public static void main(String[] args)throws Exception {
ServerSideSAXParser ref = new ServerSideSAXParser();
ref.parseString("<start><![CDATA['This is the cdata']]></start>");
}
}

Thanks for providing the code.

Hello,

I have still a lot to learn in programming and I'm sorry for this stupid question.
But i was wondering how to use this code ?

Can you modify it to read txt files or html?

Will anyone be kind enough to reply to this question?

XML *is* text. But text is not normally XML, and neither is HTML. So, no, you can't use a SAX parser for reading text files in general or HTML.

But the question is: why would you want to? What are you trying to accomplish?

Many thanks for the help

In fact i'm doing some web scraping and want to get some data found in between the CData.

I have found a nice code doing part of this job.

HTML is not generally XML. I suspect that this code will not work for 99% of all web pages in existence (doesn't mean it won't work for any particular page you're interested in, of course, especially if that page happens to be XHTML).
