This makes it available for all form associated elements and not just
select and input elements. It also makes it more spec compliant,
especially around the form attribute.
The main thing missing is re-associating form elements with a form
attribute when the form attribute changes or an element with an ID
is inserted/removed or has its ID changed.
This necessitated making HTMLParser ref-counted, and having it register
itself with Document when created. That makes it possible for scripts to
add new input at the current parser insertion point.
There is now a reference cycle between Document and HTMLParser. This
cycle is explicitly broken by calling Document::detach_parser() at the
end of HTMLParser::run().
This is a huge progression on ACID3, from 31% to 49%! :^)
This implements basic support for dynamic markup insertion, adding
* Document::open()
* Document::write(Vector<String> const&)
* Document::writeln(Vector<String> const&)
* Document::close()
The HTMLParser is modified to make it possible to create a
script-created parser which initially only contains a HTMLTokenizer
without any data. Aditionally the HTMLParser::run method gains an
overload which does not modify the Document and does not run
HTMLParser::the_end() so that we can reenter the parser at a later time.
Furthermore all FIXMEs that consern the insertion point are implemented
wich is defined in the HTMLTokenizer. Additionally the following
member-variables of the HTMLParser are now exposed by getter funcions:
* m_tokenizer
* m_aborted
* m_script_nesting_level
The HTMLTokenizer is modified so that it contains an insertion
point which keeps track of where the next input from the Document::write
functions will be inserted. The insertion point is implemented as the
charakter offset into m_decoded_input and a boolean describing if the
insertion point is defined. Functions to update, check and {re}store the
insertion point are also added.
The function HTMLTokenizer::insert_eof is added to tell a script-created
parser that document::close was called and HTMLParser::the_end() should
be called.
Lastly an explicit default constructor is added to HTMLTokenizer to
create a empty HTMLTokenizer into which data can be inserted.
