Re: Improvements to gnuapl

[Dr . Jürgen Sauermann]

Hi Blake,

You're correct. Another problem in HTML is unquoted attribute values in 
HTML tags.

I should have said "One can use ⎕XML for decoding HTML pages and the 
like as long as
they obey the fundamental XML encoding rules".

I believe it would be possible to make ⎕XML tolerate some of these HTML 
quirks,
but I wonder if it is worth the effort.

Best Regards,
Jürgen
