Conversion of .aspx into .rhtml

Hi Everybody,

    I am working on a project which is implemented in .net

framework before ( vb and asp ). Its a website about articles, columns
etc. I want to implement it in ruby platform.
I have problem in designing , As it is already ready but i
cant use it due to asp tags and different logic used using .net. I
want to get only HTML code from the .aspx files. Does anybody can
suggest something to solve this problem???
