Question

I have student.xml file and am parsing this file using SAX Parser and now I need to store data into MySQL Database and so what approach is recommended.

Code:

package sax;

    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 ReadXML extends DefaultHandler{

        public void characters(char[] ch, int start, int length) throws SAXException {
            String s =new String(ch, start, length);
            if(s.trim().length()>0) {
                System.out.println("    Value: "+s);
            }
        }

        public void startDocument() throws SAXException {
            System.out.println("Start document");
        }

        public void endDocument() throws SAXException {
            System.out.println("End document");
        }

        public void startElement(String uri, String localName, String name,
                Attributes attributes) throws SAXException {
            System.out.println("start element : "+name);

        }

        public void endElement(String uri, String localName, String name) throws SAXException {
            System.out.println("end element");
        }

        public static void main(String[] args) {
            ReadXML handler = new ReadXML();

            try { 
                SAXParserFactory factory = SAXParserFactory.newInstance();

                SAXParser saxParser = factory.newSAXParser();

                saxParser.parse("student.xml", handler); 
            } catch (Exception e) {
                e.printStackTrace();
            }
        }

    }

Answer 1

I would create a set of tables that represent the data contained in students.xml and then populate them as you parse the data.
