XSLT to transform one XML file to another and display as HTML

[GStar999]

I have the following two xml files:

1
sample questionnaire

    1
    Q1) Enter some free text
    2
    1
    
             
2    
    Q2) Select any of the choices  
    6
    1
    
    Choice1
        Choice2
        Choice3

1
1234
This is some text

    Choice 2

How do you use xslt to add the response for this user to questionnare file and display as HTML form so in the above example the textbox will be populated with 'This is some text' and the dropdown will have 'Choice 2' selected? Some example xslt implementing the above would be very helpful to get started. ideally I would like to do this in asp.net
