The main library itself is just a function with a bunch of callbacks:

declCallBack <- for <!doctype> style tags
endCallBack  <--- for start and end tags

I was thinking of making an interface where certain functions are
called based on the HTML tag as well as this generic interface.
In either case it should be easy to add support for Javascript.
