Displaying random xml
<p>I have an xml which contains 10 buttons named stage 1 to stage 10. in each button(stages) there are 5 xml inside which contains 5 questions. How can I randomly display those 5 xml in each stage buttons without repeating the other again? and after all 5 xml's are randomly displayed it will intent to a certain xml that I want?
The flow is like this:</p>

<p>A1>q1,q2,q3,q4,q5 - after all the 5 questions displayed randomly, it will intent to a certain page, lets say list of stages. Then I will pick another level for example stage2 then repeat the process again A2>q1,q2,q3,q4,q5.</p>
