validation puzzle ("OMITTAG NO" error)

kj


Here's a puzzle I can't figure out.

I visited the page http://validator.w3.org, and confirmed that it
validates itself.

Then I *saved* it to my docroot directory using my browser's save-as
function, and then tried to submit this saved page for validation.
Now it generates 17 errors, of the form:

end tag for "link" omitted, but OMITTAG NO was specified.

I can't understand why the saved version of the same page produces
this error. The page I saved can be seen here:

http://www.panix.com/~kynn/v/

As you can see, it looks pretty much the same as the original.
I've also compared the source for both pages (using the browser's
show-source command), and I can't see any significant difference.

What's going on?

OK, here's a second question, a more important one, in a way. I
have 3 books on HTML, and not one of them has helped me at all with
this question. There are a zillion books on HTML in the market.
Among these, which one would have helped me with this question? In
other words, next to the W3C specs (which I find very difficult to
read somehow), what's the "bible" of HTML? The book that would
cover even obscure problems like this one?

Thanks!

Pretty much isn't good enough.
The original has this:
<link rev="made" href="mailto:ww ***********@w3. org" />
Your has this:
<link rev="made" href="mailto:ww ***********@w3. org">

The difference is the slash at the end, which causes the error.

Need to look closer then ;-)

Probably any of them. You just need to understand the difference
between XHTML and HTML.

It's not an obscure problem, and for me the specs are good enough ;-)

The validator interface has been written as Appendix C XHTML, served as
HTML. When your browser saved it, it removed the slashes that form
empty-element start-tags. For example, in the original:

<link rev="made" href="mailto:ww ***********@w3. org" />

In your saved version:

<link rev="made" href="mailto:ww ***********@w3. org">

As elements must be closed in XML documents, the validator complains
about the latter, as well as the other link, meta, img, br, and input
elements.

If you change the document type to HTML 4.01 Strict, remove the prolog,
and the xml:lang and xmlns attributes, the errors should disappear.

Sorry. I wouldn't know.

This is perhaps a very simple and stupid question! How do you run a specific function (with actual values for the parameters) within a module from the command prompt? That is, with "python ..." For instance, how do I run hello_msg("Hello no ", 3), which is a function within the module hello.py, from the console? def hello_msg(msg, num): print msg + str(num ** 3) +'!'

Hi! Okay, so positions on "text/html" XHTML are totally contradicting. Anyway! I hope there's more consensus about "application/xml" XHTML. I've recently learned that Opera 9.0b2 does not only evaluate HTTP header, BOM and XML declaration to determine the character encoding of an XHTML document sent as "application/xml", but also the "meta" element. For example, <http://schneegans.de/sv/test-cases/?case=meta-only-encoding> is rendered...
