I wanted to know how can we create a.xml file through java with the given data.
For example: book saler.
data given through java are
1)Sl no
2)Book name
3Book type
4)Book price
i want a xml file generated through the java code
can anyone help me out?
The below code is written using dom4j in java.. You can look at some other examples in dom4j..
But, here is the short version..
Document document = DocumentHelper.createDocument();
Element root = document.addElement( "BookSeller")
QName qNameReqId = new QName("SerialNo","SlNo");
QName qBookName = new QName("BookName","Book Name");
QName qBookType= new QName("BookType","Book Type");
QName qBookPrice= new QName("BookPrice","Book Proce");
Element reqIdElement = root.addElement( qNameReqId ).addText( 1 );
Element bookNmElement = root.addElement( qBookName ).addText( "Java/XML");
Element bookTypeElement = root.addElement( qBookType).addText( "LEARNING");
Element bookPriceElement = wtnElement.addElement(qBookPrice).addText( "100$");
StringWriter stringWriter= new StringWriter();
XMLWriter xmlWriter = new XMLWriter(stringWriter);
xmlWriter.write(document);
xmlString=stringWriter.toString();
I think something like this could work for you.
import org.xml.sax.ContentHandler;
import org.xml.sax.SAXException;
import org.xml.sax.helpers.AttributesImpl;
import org.xml.sax.ContentHandler;
public void writeSAX(ContentHandler ch) throws SAXException {
String name = "Some book name";
String type = "Some book type";
String price ="$10.00";
AttributesImpl attrs = new AttributesImpl();
ch.startElement("","Book type","", attrs);
attrs = new AttributesImpl();
char[] chars = type.toCharArray();
ch.characters(chars,0,chars.length);
ch.startElement("","Book Name","", attrs);
char[] chars = name.toCharArray();
ch.characters(chars,0,chars.length);
ch.endElement("","Book name","");
ch.startElement("","Book Price","", attrs);
char[] chars = price.toCharArray();
ch.characters(chars,0,chars.length);
ch.endElement("","Book Price","");
ch.endlement("", "Book Type","");
}
i have done like this..
but the problem with this is i want to add more than one book details. i am able to add only one book detais..

The javadocs are not clear on this subject, but I have a suggestion.
I know that with "regular" DOM processing, an object can only appear in the Document at one place. There is a comment in the insertBefore method of the Node interface to this effect.
If this is the problem, then create a new Order object before you setBookName.
