Warning: newbie question.

This may be a bug in Wordpress, or it may be my misunderstanding of
plain ol' XHTML; it affects both Gecko and IE.

A user wrote a post using the Wordpress editing interface, which
generated the following XHTML.

<div id="1"><p><strong /></p></div>
<div id="2">...</div>

Note that <strong /> -- it makes Firefox 1.5.0.7 generate this DOM:

<div id="1"><p><strong></strong></p></div>
<div id="2"><strong>...</strong></div>

That is, using an inline element in the first div influences the DOM
generated in the second div. Isn't that wrong?

If you're serving XHTML as text/html (which means browsers handle it as
HTML, not XHTML), you have to follow the guidelines in Appendix C of
XHTML 1.0, which this does not:

> <div id="1"><p><strong /></p></div>

What he said. You need to force it as XML of some sort
(application/xhtml+xml in this case); otherwise, you get tag soup mode.

Yes, I am serving it as text/html.

In case it would be a point of interest, the W3 validator accepted it as
XHTML transitional.

I suppose I should go file a bug in Wordpress re: Appendix C. I'm
assuming you're referring to Appendix C.3?

Like I said, you need to serve as application/xhtml+xml if you want that
sort of XML functionality to work. I'd recommend not using that unless
you can dynamically change it based on whether or not you're serving
XML.

Yeah, that's a bug in the validator (bug 1500, if you care).

The bug there is the HTML Working Group, not the Validator...
