Copy one text file to another text file and delete last line

Question

Hi all wonder if someone can help, i want to be able to copy one text file to another text file and remove the last line of the first text file. So currently i have this method:
Writer output = null;
         File file = new File("playerData.xml");
         try {
               output = new BufferedWriter(new FileWriter(file, true));
               output.write("\t" + "<player>" + "\n");
               output.write("\t" + "\t" + "<playerName>" + playerName + "</playerName>" + "\n");
               output.write("\t" + "\t" + "<playerScore>" + pointCount + "</playerScore>" + "\n");
               output.write("\t" + "\t" + "<playerTime>" + minutes + " minutes " + seconds + " seconds" + "</playerTime>" + "\n");
               output.write("\t" + "</player>" + "\n");
               output.write("</indianaTuxPlayer>" + "\n");
              output.close();
              System.out.println("Player data saved!");
         catch (IOException e) {
               e.printStackTrace();
          }However each time the method is run i get the "</indianaTuxPlayer>" line repeated, now when i come to read this in as a java file i get errors becuase its not well formed. So my idea is to copy the original file, remove the last line of that file, so the </indianaTuxPlayer> line and then add this to a new file with the next data saved in it. So i would end up with something like this:
<?xml version="1.0" encoding="UTF-8"?>
<indianaTuxPlayers>
     <player>
          <playerName>Default Player</playerName>
          <playerScore>0</playerScore>
          <playerTime>null minutes null seconds</playerTime>
     </player>
     <player>
          <playerName>Default Player</playerName>
          <playerScore>0</playerScore>
          <playerTime>null minutes null seconds</playerTime>
     </player>
     <player>
          <playerName>Default Player</playerName>
          <playerScore>0</playerScore>
          <playerTime>null minutes null seconds</playerTime>
     </player>
</indianaTuxPlayers>
However after all day searching the internet and trying ways, i have been unable to get anything working, could anyone give me a hand please?

I would go the XML route too, but for fun, open a file as a BufferedWriter and do this:
void copyAllButLastLine(File src, BufferedWriter tgt) throws IOException {
    BufferedReader in = new BufferedReader(new FileReader(src));
    try {
        String previous= in.readLine();
        for (String current = null; (current = in.readLine()) != null; previous=current) {
            tgt.write(previous);
            tgt.newLine();
    } finally {
        in.close();
}
