reading and writing to and from xml file on android

Question

This is part of my string.xml file on an application that I'm trying to create:

<array name="users">
    <item>
        <user_name>u1</user_name>
        <password>p1</password>
        <email>aaa@aaa</email>
    </item>
    <item>
        <user_name>u2</user_name>
        <password>p2</password>
        <email>bbb@bbb</email>
    </item>
    <item>
        <user_name>u3</user_name>
        <password>p3</password>
        <email>ccc@ccc</email>
    </item>
</array>

I have a problem reading the "users" two-dimensional array into a two-dimensional array on the java file. I've already created a class name "User" for the array. I'm quite stuck here. Can anybody give me a hand? Thanks

Provide some code of what you already tried. Otherwise, this is a "Gimme the Codz" question. — Lukas Knuth, Mar 16 '13 at 15:39
Have you tried getResources().getStringArray(R.array.users); — Pragnani, Mar 16 '13 at 15:39
Of course I have, but it gives me only one dimension array. How do I get the username and password of every item? for function was of no use to me there — Itzick Binder, Mar 16 '13 at 15:44

strings.xml is not for what you are trying to do here. It is supposed to have all strings that are displayed to the user to provide multi-language support.

If you want to store your app's domain data to XML file, you can create one in the assets folder and read it.

It's ok. I've solved it. Here is my code:

String[] userArray = getResources().getStringArray(R.array.users);
User[] arr = new User[3];
for(int i=0 ; i<userArray.length ; i++)
arr[i] = new User(userArray[i]);

and this is my "User" class constructor:

public User(String str)
{
    int num;
    str = str.substring(1);
    num = str.indexOf(' ');
    user_name = str.substring(0,num);
    String substr = str.substring(num+1);
    num = substr.indexOf(' ');
    password = substr.substring(0,num);
    email = substr.substring(num+1);
}

In that way I get an array of "User".
