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

[jimranjava]

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,
