Apparently for a beta (5.0 beta, maybe) they had something like
TEXTAREA... maybe it was called HTMLAREA. Anyway, you could enter
rich text, with bold, italic, etc. IE would then send it as text with
HTML markup. But they took it out :-(

I don't like spreadsheets. I code in Emacs. I read my mail in
Emacs. I love Emacs. I never ever use spreadsheets, why use them for
this one thing?

I'm unclear, once I've created the model how do I create the store
based on that model?

I've never really understood what UML languages really offer over just
reading something and thinking about it.

The WYSIWYG editor would really like to know what image you are
inserting. The editor of course can't find any image named $foo. It
would be easier for it to understand
<IMG SRC="sample.gif" replace="$foo">
Or whatever.

Yes. Like I said before, HTMLTag is fairly close to equivalent to the
structure I used. The transformer I used that implemented the
ZPT-style attribute-based language also could be used to transform the
HTML from one form to another. I felt this was best handled as a
transformation, not a method of the HTML parse tree.
To give an example of HTML transformation, here's the code to change
all A HREF tags to use redirects (so you can log it) and have some
JavaScript to hide you are doing that:
def a_transform(node):
if not node.has_key("href"):
# It must be a <a name> node, which we don't care about
return node
loc = node["href"]
if loc[:7] != "http://"; and loc[:8] != "https://":
# It's a local site or something, so we don't need to log
return node
node["href"] = '/redirect.cgi?loc=%s' % urllib.quote(loc)
node["onMouseOver"] = "window.status='%s'" % htmlEncode(loc)
node["onMouseOut"] = "window.status=''"
return node
# This is all the cruft that sets up the tranformation.
# This would all be packaged up in a useful function, if given
# a clearer context.
htmlTrans = HTMLTransformer()
tagTrans = TagTransformer()
htmlTrans.addTransformer(tagTrans)
tagTrans.addTransformer("a", a_transform)
htmlSource = HTMLParser(htmlText).parse()
HTMLUnparser(htmlTrans.transform(htmlSource)).unparse()
