Managed to do this with JavaScript. It works in Internet Explorer 9 and Chrome 15, I haven't tested older versions. It should work in Firefox 11 when support for outerHTML is added (see here), meanwhile there are some custom implementations available on the web. An excercise for the reader is to get rid of trailing indentation (until I make time to finish it and update this answer).

I'll also mark this as community wiki for easy editing.

Please note that you'll have to reformat the example to use tabs as indentation, or change the regex to work with spaces.



    
        Hello, World!
    
    
                    <html>
                <head>
                    <title>Hello World Example</title>
                </head>
                <body>
                    Hello, World!
                </body>
            </html>
        
                    class HelloWorld
            {
                public static int Main(String[] args)
                {
                    Console.WriteLine(&quot;Hello, World!&quot;);
                    return 0;
                }
            }
