How to populate database table from a file in ecplise?

I'm working on small Android project in eclipse. I created a database table but instead of populating the columns using EditText control, I want to populate it using data from a file (txt or xml). I have a table shown below populated using EditText.

Database class:

@Override
public void onCreate(SQLiteDatabase sqldb) {
myTableQuery="CREATE TABLE staff (staff_ID INTEGER PRIMARY KEY, staff_Name TEXT, appointment_Day TEXT, " +
            "start_Time TEXT, end_Time TEXT, comment TEXT)";

    sqldb.execSQL(myTableQuery);
}

public void AddStaff(String id, String name, String day, String start, String end, String comment){

    SQLiteDatabase sqldb=this.getWritableDatabase();

    ContentValues values = new ContentValues();
    values.put("staff_ID", id);
    values.put("staff_Name", name);
    values.put("appointment_Day", day);
    values.put("start_Time", start);
    values.put("end_Time", end);
    values.put("comment", comment);

    sqldb.insert("staff", null, values);
    sqldb.close();


}

AddActivity class:

public void AddRowItemTable(View v){


    EditText staff_id = (EditText) findViewById(R.id.sId);
    EditText staff_name = (EditText) findViewById(R.id.sname);
    EditText day = (EditText) findViewById(R.id.day);
    EditText start = (EditText) findViewById(R.id.start);
    EditText end = (EditText) findViewById(R.id.end);
    EditText comment = (EditText) findViewById(R.id.comment);

    String id = staff_id.getText().toString();
    String name = staff_name.getText().toString();
    String d = day.getText().toString();
    String s = start.getText().toString();
    String e = end.getText().toString();
    String c = comment.getText().toString();

    MainActivity.myDB.AddStaff(id, name, d, s, e, c);
    Intent newintent=new Intent(this, MainActivity.class);
    startActivity(newintent);

}

Instead of doing it this way, how can I read data from file to populate it. File looks like this.

<?xml version="1.0" encoding="utf-8"?>
<staff>

    <record staff_ID="S1" staff_Name="John" appointment_Day="Monday" start_Time="9" end_Time="12" comment="xxx"/>
    <record staff_ID="S2" staff_Name="Bob" appointment_Day="Monday" start_Time="10" end_Time="11" comment="xxx"/>

</staff>

Any help..??
