What's the problem? Compile error? Runtime exceptions? Something else?

using sax parser for reading xml file

hi
i m telling you how can you use the sax parser::

1)first of all you have to take your xml string into the form of InputSource
2)then create an instance of SAXParserFactory (coz you will create an instance of the SAXParser with this)
3)create an instance of saxparser
4)validate it
5)call "parser" method of the saxparser class which takes two parameter, that is::
a)InputSource
b)instance of the class which extends DefaultHandler class
6)now it will automatically calls the overloaded methods of the class DefaultHandler. And you only need to implement your code as you want.


I am giving you an example code, it will help you a lot.

method::
viewXML( String xmlStr )
{
try
{
byte[] xmlByteArray = xmlStr.getBytes();//k
ByteArrayInputStream xmlStream = new ByteArrayInputStream( xmlByteArray );//k
org.xml.sax.InputSource xmlReader = new org.xml.sax.InputSource( xmlStream );//k
SAXParserFactory spfactory = SAXParserFactory.newInstance();
try
{
SAXParser saxParser = spfactory.newSAXParser();//k
spfactory.setValidating(true);//k
saxParser.parse( xmlReader, new SaxParser());//k
}
catch (Throwable err)
{
err.printStackTrace ();
System.out.println("exception in SAXparser init["+err+"]");
}
}
catch(Exception e)
{
System.out.println("exception in factory init["+e+"]");
}
}
