How to create new XML file using retreived XML content by using SAX API?

Question

hi all,
* How to create new XML file using retreived XML content by using SAX ?
* I have tried my level best, but output is coming invalid format, my code is follows,
XMLFileParser.java class :-
import java.io.StringReader;
import java.io.StringWriter;
import javax.xml.transform.OutputKeys;
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerConfigurationException;
import javax.xml.transform.TransformerException;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.dom.DOMResult;
import javax.xml.transform.sax.SAXSource;
import javax.xml.transform.sax.SAXTransformerFactory;
import javax.xml.transform.sax.TransformerHandler;
import javax.xml.transform.stream.StreamResult;
import org.w3c.dom.Document;
import org.xml.sax.Attributes;
import org.xml.sax.InputSource;
import org.xml.sax.SAXException;
import org.xml.sax.helpers.XMLFilterImpl;
public class PdfParser extends XMLFilterImpl {
    private TransformerHandler handler;
    Document meta_data;
    private StringWriter meta_data_text = new StringWriter();
    public void startDocument() throws SAXException {
    void startValidation() throws SAXException {
        StreamResult streamResult = new StreamResult(meta_data_text);
        SAXTransformerFactory factory = (SAXTransformerFactory) SAXTransformerFactory.newInstance();
        try
            handler = factory.newTransformerHandler();
            Transformer transformer = handler.getTransformer();
            transformer.setOutputProperty(OutputKeys.ENCODING, "UTF-8");
            transformer.setOutputProperty(OutputKeys.INDENT, "yes");
            handler.setResult(streamResult);
            handler.startDocument();
        catch (TransformerConfigurationException tce)
            System.out.println("Error during the parse :"+ tce.getMessageAndLocation());
        super.startDocument();
    public void startElement(String namespaceURI, String localName,
            String qualifiedName, Attributes atts) throws SAXException {
        handler.startElement(namespaceURI, localName, qualifiedName, atts);
        super.startElement(namespaceURI, localName, qualifiedName, atts);
    public void characters(char[] text, int start, int length)
            throws SAXException {
        handler.characters(text, start, length);
        super.characters(text, start, length);
    public void endElement(String namespaceURI, String localName,
            String qualifiedName) throws SAXException {
        super.endElement("", localName, qualifiedName);
        handler.endElement("", localName, qualifiedName);
    public void endDocument() throws SAXException {
    void endValidation() throws SAXException {
        handler.endDocument();
        try {
            TransformerFactory transfactory = TransformerFactory.newInstance();
            Transformer trans = transfactory.newTransformer();
            SAXSource sax_source = new SAXSource(new InputSource(new StringReader(meta_data_text.toString())));
            DOMResult dom_result = new DOMResult();
            trans.transform(sax_source, dom_result);
            meta_data = (Document) dom_result.getNode();
            System.out.println(meta_data_text);
        catch (TransformerConfigurationException tce) {
            System.out.println("Error occurs during the parse :"+ tce.getMessageAndLocation());
        catch (TransformerException te) {
            System.out.println("Error in result transformation :"+ te.getMessageAndLocation());
} CreateXMLFile.java class :-
Sax.startDocument();
Sax.startValidation();
Sax.startElement("", "pdf", "pdf", new AttributesImpl());
Sax.startElement("", "basic-metadata", "basic-metadata", new AttributesImpl());          
String xmp_str = new String(meta_data.getByteArray(),"UTF8");
char[] xmp_arr = xmp_str.toCharArray();
Sax.characters(xmp_arr, 0, xmp_arr.length);
Sax.endElement("", "pdf", "pdf");
Sax.endValidation();
Sax.endDocument();
Sax.endElement("", "basic-metadata", "basic-metadata");* In CreateXMLFile.java
class, I have retreived the xml content in the meta_data object, after that i have converted into character array and this will be sends to SAX
* In this case , the XML file created successfully but the retreived XML content added as an text in between basic-metadata Element, that is, retreived XML content
is not an XML type text, it just an Normal text Why that ?
* Please help me what is the problem in my code?
Cheers,

Answer 1

Sax.startDocument();
Sax.startValidation();
Sax.startElement("", "pdf", "pdf", new AttributesImpl());
Sax.startElement("", "basic-metadata", "basic-metadata", new AttributesImpl());          
String xmp_str = new String(meta_data.getByteArray(),"UTF8");
char[] xmp_arr = xmp_str.toCharArray();
Sax.characters(xmp_arr, 0, xmp_arr.length);
</code><code>Sax.endElement("", "basic-metadata", "basic-metadata");</code>
<code class="jive-code jive-java">Sax.endElement("", "pdf", "pdf");
Sax.endValidation();
Sax.endDocument();     
* I HAVE CHANGED MY AS PER YOUR SUGGESTION, NOW SAME RESULT HAS COMING.
* I AM NOT ABLE TO GET THE EXACT OUTPUT.,WHY THAT ?
