Re: lynx-dev Using other HTML parsers in Lynx

[Mooneer Salem]

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

declCallBack <- for <!doctype> style tags
startCallBack
endCallBack  <--- for start and end tags
textStartCallBack
textCallBack
textEndCallBack
commentStartCallBack
commentCallBack
commentEndCallBack

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.
