Javascript failing xhtml [xhtml newbe]

[Jean Pierre Daviau]

Hi,

<script language="javas cript" type="text/javascript">
if(navigator.ap pName.indexOf(" Netscape") != -1){
document.writel n('<link rel="stylesheet " href="~styles/aquarelle_ns.cs s"
type="text/css" media="screen" title="base" />');
}else{
document.write( '<link rel="stylesheet " href="~styles/aquarelle.css"
type="text/css" media="screen" title="base" />');
}
</script>

<style type="text/css">
....
</style>
</head>
------------------------------------
Error Line 39 column 118: document type does not allow element "link" here.
....xt/css" media="screen" title="base" />');The element named above was
found in a context where it is not allowed. This could mean that you have
incorrectly nested elements -- such as a "style" element in the "body"
section instead of inside "head" -- or two elements that overlap (which is
not allowed).

One common cause for this error is the use of XHTML syntax in HTML
documents. Due to HTML's rules of implicitly closed elements, this error can
create cascading effects. For instance, using XHTML's "self-closing" tags
for "meta" and "link" in the "head" section of a HTML document may cause the
parser to infer the end of the "head" section and the beginning of the
"body" section (where "link" and "meta" are not allowed; hence the reported
error).

What can I do?

The most important issue: document.writel n() does not work in XHTML, if it's
served as application/xhtml+xml. I assume that you are going to do this (at
least with content negotiation, for browsers that support it), because
XHTML is just another form of tagsoup, if served as text/html.

Script snippets that contain '<' or '&' characters must be enclosed in
<[CDATA[ .. ]]> marked sections, otherwise the validator will not parse the
document as you intend it to do (browsers are more tolerant, but I would
not count on it).

This does not happen, if you stick to HTML, because the STYLE element has
the content model CDATA, which means that the parser ignores (e.g. does not
interpret a '<' as the start of a tag) everything until it finds the first
'</' followed by a character 'a..z' or 'A..Z'.

How come this page validate sending
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
It does not use the crazy CDAT[[]]?

(a) That meta tag is mostly rubbish and the real http header will trump it
every time

(b) Validation checks conformance to the DTD. That is entirely independent
of the content type.

(c) You said it didn't validate!

Dont misunderstand me, I am just trying to figure out :-)

I did not express myself well.

I was talking about mypage http://www.jeanpierredaviau.com/echangeTidy.html

not this one:

Does not it send text/html content? It is suppose to be useless has I red
in the article you refered me.

======
If you use XHTML, you should deliver it with the application/xhtml+xml
MIME type. If you do not do so, you should use HTML4 instead of XHTML.
The alternative, using XHTML but delivering it as text/html, causes
numerous problems that are outlined below.
==============


My question is: is xhtml possible?

Yes, but that has nothing to do with the <meta> tag you put in it.

Sending XHTML as text/html gives you none of the benefits of XHTML (which
are of use to only a very small proportion of authors today anyway), and is
actively harmful in those (admittedly small proportion of) browsers which
implement HTML correctly.

In 2005 it is mostly pointless and rather impractical.
