I created a XML file with java which looks like this:

<?xml version="1.0" encoding="UTF-8" ?>
- <music>
- <mp3>
  <name>Audioplacid - Heaven 0.9.1.mp3</name>
  <size>11911528</size>
  <path>D:\Mp3</path>
  <ext>mp3</ext>
  <added>1112185739331</added>
  </mp3>
- <mp3>
  <name>E-Nature - Silent Nature.mp3</name>
  <size>12449920</size>
  <path>D:\Mp3\E-Nature</path>
  <ext>mp3</ext>
  <added>1065606457000</added>
  <comment />
  <rating />
  <hidden />
  </mp3>
.....

I tried several times to add more than one root node to the xml file but
everytime I want to do that I either get an error or the first root node
will be overwritten with the second root node.

is it possible to have more than one root node in the same file?
any tips or suggestions?

my current java code for this function looks like this:

public Document addXmlContent(String directory, String discName, String
archiveName)
    throws ParserConfigurationException {

        Vector filesInDirectory = fillDirInVector(directory);
       
        /* get an xml doc */
        DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
        DocumentBuilder builder = factory.newDocumentBuilder();
        Document xmldoc = builder.newDocument();
       
        // create the root node
        // NAME OF ARCHIVE
        Element docRoot = xmldoc.createElement(archiveName);
       
        // VECTOR READING LOOP START
        for (int i = 0; i < filesInDirectory.size(); i += 5) {
       
           /* create a row node */
           // NAME OF DISC
           Element rowElement = xmldoc.createElement(discName);
       
           /* create the column nodes and append each to the row node */
           Element columnElement;
           Text textData;
       
           // FILE NAME
           columnElement = xmldoc.createElement("name");
           textData = xmldoc.createTextNode((String) filesInDirectory
                   .elementAt(i));
           columnElement.appendChild(textData);
           rowElement.appendChild(columnElement);
       
           // FILE SIZE
           columnElement = xmldoc.createElement("size");
           textData = xmldoc.createTextNode((String) filesInDirectory
                   .elementAt(i + 1));
           columnElement.appendChild(textData);
           rowElement.appendChild(columnElement);
       
           // SUBPATH IN DIRECTORY
           columnElement = xmldoc.createElement("path");
           textData = xmldoc.createTextNode((String) filesInDirectory
                   .elementAt(i + 2));
           columnElement.appendChild(textData);
           rowElement.appendChild(columnElement);
       
           // FILE EXTENSION
           columnElement = xmldoc.createElement("ext");
           textData = xmldoc.createTextNode((String) filesInDirectory
                   .elementAt(i + 3));
           columnElement.appendChild(textData);
           rowElement.appendChild(columnElement);
       
           // LAST MODIFICATION DATE
           columnElement = xmldoc.createElement("added");
           textData = xmldoc.createTextNode((String) filesInDirectory
                   .elementAt(i + 4));
           columnElement.appendChild(textData);
           rowElement.appendChild(columnElement);
       
           // PERSONAL COMMENT FOR FILE
           columnElement = xmldoc.createElement("comment");
           textData = xmldoc.createTextNode("");
           columnElement.appendChild(textData);
           rowElement.appendChild(columnElement);
       
           // RATE SPECIFIC FILE
           columnElement = xmldoc.createElement("rating");
           textData = xmldoc.createTextNode("");
           columnElement.appendChild(textData);
           rowElement.appendChild(columnElement);
       
           // SHOW ARCHIVE ONLY IF PASSWORD WAS ENTERED
           columnElement = xmldoc.createElement("hidden");
           xmldoc.createTextNode("n");
           columnElement.appendChild(textData);
           rowElement.appendChild(columnElement);
       
           /* append the row node to the root node */
           docRoot.appendChild(rowElement);
       
           /* VECTOR READING LOOP END */
        }
       
        /* append the root node to the empty document */
        xmldoc.appendChild(docRoot);
       
        return xmldoc;
    }
