Error while adding elements from one xml file to new xml file

HI,

Now i'm going through a project regarding xml manipulation. I want to rewrite the data from one xml file to another. I've attatched my coding and error showing in console. As i'm new to this project i don't know whether this concept is write or not.Could anybody help me to know about this problem?

Would appreciate any pointers..

coding:

import java.io.StringReader;
import java.util.Iterator;
import java.util.List;
import org.jdom.Document;
import org.jdom.Element;
import org.jdom.JDOMException;
import org.jdom.input.SAXBuilder;

public class Test3 {
    static Document profile = new Document();
    static Element html     = new Element("html");

    public static void main(String[] args) throws JDOMException {
        try{
            profile.setRootElement(html);
        String xml = "<?xml version=\"1.0\" encoding=\"UTF-8\"?><myhtml> <body> <h1 align=\"center\">Profile</h1><hr /> <div class=\"centered\"> <table><tr><td><strong>Name: </strong></td> <td>A</td> </tr> <tr> <td><strong>Age: </strong></td> <td>23</td> <td>programmer</td></tr><tr><td><strong>Email: </strong></td><td>[email protected]</td></tr></table></div><hr /></body></myhtml>";
        SAXBuilder builder = new SAXBuilder();
        Document doc = builder.build(new StringReader(xml));
        listChildrenOrg(doc.getRootElement(), 0);
}
        catch(Exception e){
            e.printStackTrace();
        }
    }

     private static void listChildrenOrg(Element root, int depth) {
        System.out.println(root.getName());
        List children = root.getChildren();
        System.out.println(children.size());
        Iterator iterator = children.iterator();
        while (iterator.hasNext()) {
             Element child = (Element) iterator.next();
             System.out.println(child);
             body.addContent(((Element)child.clone()).detach());
             listChildrenOrg(child, depth+1);
               }
}
}

output file is blured one..

you have to clone and detach the child from its parent element before adding it to the new parent:

html.addContent(((Element)child.clone()).detach());

The issue is here:

Element child = (Element) iterator.next();
System.out.println(child);
html.addContent(child);

child is reference to the body element of the original xml document. Its parent is myhtml You cannot add this as child of another new element in this way.

You need to create a new element for the new xml document. I suggest you to study on "Reference" in Java.
