XMLHTTP

[Philipp Lenssen]

A nice way to dynamically update HTML on a page (without leaving the
page) is to use document.innerHTML and XMLHTTP in JavaScript, then
communicate with the server via XML snippets (plus some server side
scripts of course, I use PHP5+MySQL). If you want to see an example,
you can take a look at my chat:

(And I was inspired by Google Suggest, which uses XMLHTTP.)

Of course, this can also be used for form validation and similar tasks.

So, wouldn't that mean HTML was also naked (not being real SGML, as you
say)?

Yes, the notion of text/html as SGML is bogus as well. However, HTML
4.01 provides useful features over the early honest tag soup, and the
soupness of text/html is less likely to contaminate SGML than XML.
Again, for me the choice between XHTML and HTML is an arbitrary one. As
I said I prefer the style of always-closed p's, always-quoted
attributes, always using both attribute-name and attribute-value, and
having the same syntax as XML.
text/html user agents don't enforce your code style preference even if
you pretend to use XHTML. You need external tools for that enforcement.
You can enforce a similar code style with HTML using external tools.
(Try the "fussy mode" of PageValet--no custom DTD required.)
I think it's
equally silly to say "avoid XHTML because there are problems". There
are *always* problems no matter what language you choose on the web.

As far as I can tell, the problems of XHTML served as text/html are a
proper superset of the problems of HTML 4.01 served as text/html. In
general, one is willing to take new problems only in exchange for some
benefits.
