List menu by Parse XML in J2ME

I want to create menu from XMLFile. My xml is like this

<?xml version="1.0" encoding="UTF-8"?>
<root>
<parent title="Layanan Anda">
    <menu title="Info Kartu">
        <submenu title="Informasi Saldo">
            <input type="numberpassword" length="4">Kode </input>
        </submenu>
        <submenu title="Mutasi Kartu Utama">
            <input type="numberpassword" length="4">Kode </input>
        </submenu>
        <submenu title="Mutasi Kartu Lain">
            <input type="number" length="10">Kartu</input>
            <input type="numberpassword" length="4">Kode </input>
        </submenu>
        <submenu title="Deposito">
            <input type="number" length="10">Bilyet</input>
            <input type="numberpassword" length="4">Kode </input>
        </submenu>
    </menu>
    <menu title="Kartu Anda">
    </menu>
    <menu title="Other Info">
    </menu>
    <menu title="Isi">
    </menu>
</parent>
<parent title="Menu Favorit">
</parent>
<parent title="Recent Menu">
</parent>
<parent title="Setting">
</parent>    
</root>

In HomeScreen, list menu parent will show first. And when I click parent menu, application will show list menu from "menu" tag. When I click menu again, application will show list menu from submenu. And vice versa when I want to back to parent menu.

How can I implement this in J2ME?

Solution

Parse your XML file and create a tree structure to hold the menu/submenu items. Each node should hold the items of a single level. For example:

root: Layanan Anda, Menu Favorit, Recent Menu, Setting
- menu: Info Kartu, Kartu Anda, Other Info, Isi
  - submenu: Informasi Saldo, Mutasi Kartu Utama, Mutasi Kartu Lain, Deposito

Then use a graphical List to show the items of a node.
