I refer to Opera, and it is Opera's official position that implementing  
something like teh SVG WG proposal would be better than implementing  
something like the "commented-out" proposal. For what it is worth, it is  
also our position that these proposals are just that, and not some final  
position to defend to the death but potential bases from which to develop  
a standard.

That depends what the content you are trying to extract is. If you are  
planning to deal with all the HTML, of course you need a parser. If you  
are extracting particular things, then you can optimise and simplify...
