How to save the content withen a table into a XML file?

[Qunfeng Wang]

I have a table like this:
-----------------------------
Name Sex
Superman M
Allen M
... ...
------------------------------
columName[] = {"Name", "Sex"};
data[] = {"Superman", "M", "Allen", "M", ...};
tableModel = New MyTableModel(columnName, data);

Now I want to press a "Save" button to save this to a XML file. How do I construct the file? I'm not familer with XML.
Thanks a lot.
your sincerely letter.

hi,

i am sending sample code about how to write data to xml file. java to xml communication is possible with jdom.jar. first down load it and use this code to write data to xml file.

Needed changed...
1) This program will create "test.xml" in your "C Direcotry"
2) that file will contain one root element "Books" and several "Book"
sub tags.

<Books> <!-- this is root tag of xml file>
<Book>
<Title>AAAAAA1</Title>
<Author>asdf</Author>
<Cost>78</Cost>
</Book>
<Book>..........</Book>
<Book>..........</Book>
<Book>..........</Book>
</Books>
3)This code will write data to xml file to append data to xml file remove the commentsa and run the code.

 
import org.jdom.*;
import org.jdom.input.*;
import org.jdom.output.*;
import java.io.IOException;
import java.io.*;
 
public class WritingToXML 
{
    public WritingToXML() 
    {
      SAXBuilder builder = new SAXBuilder();
      Document myDocument = null;
      Element rootElement = null;      
      String path = "c:/test.xml";
      
    // Appending to xml file 
/*        try        
        {  
          myDocument = builder.build(path); // checks for well-formed XML or not
          rootElement = myDocument.getRootElement();   
        } 
        catch(JDOMException dexp)     {
            System.out.println("not a well formed document\n"+dexp.getMessage());      }
        catch(IOException e){ } 
    try
    {
        if(rootElement==null)          
           rootElement = new Element("Books");
    
        if(myDocument==null)          
            myDocument = new Document(rootElement);
      */
try{          
        rootElement = new Element("Books");
        myDocument = new Document(rootElement);
        
        Element bookElement;
          for(int i=1;i<6;i++)
          {
          bookElement = new Element("Book");
          bookElement.addContent(new Element("Title").addContent("AAAAAA"+i));
          bookElement.addContent(new Element("Author").addContent("asdf"));
          bookElement.addContent(new Element("Cost").addContent("78"));
 
          // Add book tag to Root tag Books
          rootElement.addContent(bookElement);
          }          
         
        XMLOutputter outputter = new XMLOutputter("     ",true);
        outputter.output(myDocument, System.out);
        System.out.println("Writting to file.......");
        outputter.output(myDocument,new FileOutputStream(path));                
        }
       catch(IOException e){e.printStackTrace();}
  }
  public static void main(String args[])
  {
   new WritingToXML();
  }
}

Hope this helps u
All The Best

But how do you automate this instead of hardcoding the data? I want to do the same thing but I need to input JTable data into the xml file line by line. Any thoughts on how to achieve it? Also, it would be helpful if you also helped me with writing filtered jtable data into the file. Thanks in adv.
