Are you viewing it in a browser only? It's possible that the browser is 
seeing HTML-ish code and (properly) ignoring all the tags, as they mean 
nothing to it. Try a "view source" and see if it's really being rendered 
properly or not.

Otherwise, maybe you ran afoul of Python escaping rules (though I don't 
see where.) Do some tests at the Python console to find out.
