Similar to this one here, in this format. This code will be generated through a button event.

<items><variable name="id"type="int">6</variable>
<itens><variable name="pos"type="int">0</variable>
<itens><variable name="count"type="int">1</variable>
<itens><variable name="id"type="int">6</variable>
<itens><variable name="max_count"type="int">1</variable>
<variable name="data"
type="octets">0100ff0001000000010000003c8601002c00020000000000010000000100000000000000009f8601009f860100e7030000e7030000050000000000404000c07944040000000000000000000000000000000000000004000000a62500009f860100a62500009f860100442100009f8601001001145000092000000385b0100</variable>
<itens><variable name="proctype"type="int">32791</variable>
<itens><variable name="expire_date"type="int">0</variable>
<itens><variable name="guid1"type="int">0</variable>
<itens><variable name="guid2"type="int">0</variable>
<itens><variable name="mask"type="int">1</variable>
</items>

  • if we think that Xmlé is just a standardization, you can generate as a string in the pattern you want and then save with the XML extension.

  • Put more examples of your code so we can help, where these values come from, want to save how and where? Leave the most complete question possible

Download this library http://repo1.maven.org/maven2/com/thoughtworks/xstream/xstream/1.4.11.1/xstream-1.4.11.jar.

And add the jar to the project

public class ManipuladorXml {

public  boolean gravarXml(List<Usuario>usuarios,String nome) {
    XStream xstream = new XStream(new DomDriver());
    String xml = xstream.toXML(usuarios);
    try {
        SalvarArquivo(nome,xml);
        return true;
    } catch (IOException ex) {
        Logger.getLogger(ManipuladorXml.class.getName()).log(Level.SEVERE, null, ex);
    }
    return false;
}

  public void lerXml(String nome) throws FileNotFoundException {
    XStream xstream = new XStream(new DomDriver());
    @SuppressWarnings("unchecked")
    List<Usuario> dados =  (List<Usuario>) xstream.fromXML(new FileReader(nome+".xml"));
    for (Usuario dado : dados) {
        System.out.println(dado.getNome());
        System.out.println(dado.getIdade());
    }
}

private void SalvarArquivo(String nome,String xml) throws IOException {
    FileWriter arq = new FileWriter(nome + ".xml");
    PrintWriter gravarArq = new PrintWriter(arq);
    gravarArq.printf(xml);
    arq.close();
}
}



public class Usuario {

private String nome;
private int idade;

public Usuario(String nomeUsuario, int serial) {
    super();
    this.nome = nomeUsuario;
    this.idade = serial;
}

@Override
public String toString() {
    return nome + " - " + idade;
}

public String getNome() {
    return this.nome;
}

public int getIdade() {
    return this.idade;
}

public void setNome(String nome) {
    this.nome = nome;
}

public void setIdade(int idade) {
    this.idade = idade;
}
}

public class Test {

public static void main(String[] args) {
    // TODO code application logic here
    ManipuladorXml xml =new ManipuladorXml();
    List<Usuario>usuarios = new ArrayList<>();
    Usuario u = new Usuario("test1", 1);
    Usuario u1 = new Usuario("teste2", 3);
    Usuario u2 = new Usuario("test3", 4);
    usuarios.add(u);
    usuarios.add(u1);
    usuarios.add(u2);
    xml.gravarXml(usuarios,"usuarios");
    try {
        xml.lerXml("usuarios");
    } catch (FileNotFoundException ex) {
        Logger.getLogger(Test.class.getName()).log(Level.SEVERE, null, ex);
    }       
}    
}
