[MarkLogic Dev General] textarea closing missing

Mon Jul 16 22:10:21 PDT 2007

Paul,

This is a difficult subject, and shows many warts from the history of 
HTML and web browser standards compliance.

What I'm suggesting is that you should be able to guide the browser into 
choosing an XHTML-compliant rendering mode, instead of the HTML-quirks 
or HTML-standards modes. Looking at your latest test, I see that it is 
not in the xhtml namespace, and is not well-formed (two elements are 
unclosed). So I wouldn't expect your test to render as XHTML - and it 
doesn't.

However, fixing the unclosed elements and the namespace may not be 
enough. While many modern browsers display xhtml correctly, they rely on 
various checks to ensure that they are seeing xhtml. But I suspect that 
you're browsing test documents on the filesystem, where browsers mostly 
can't detect XHTML.

I'm testing using a 'test.xqy' via a MarkLogic Server http port. Besides 
the fixes mentioned above, I also send "application/xhtml+xml" as the 
content-type header. Again, loading a test document from the filesystem 
probably won't work.

I see that, if I fix your sample to be well-formed xml, set the xmlns, 
and send an xhtml content-type header, both Firefox and IE6 display 
*both* textarea elements correctly.

xdmp:set-response-content-type("application/xhtml+xml"),
<html xmlns="http://www.w3.org/1999/xhtml">
<body>
&lt;textarea&gt;&lt;/textarea&gt;:
<textarea></textarea>
<p/>
&lt;textarea/&gt;:
<textarea/>
</body>
</html>

Note that the above XML still isn't valid XHTML - it doesn't have a head 
element or a title element. Neither of those problems seem to bother 
Firefox or IE6, but it might be prudent to fix them anyway.

I can't answer your deeper question, aside from pointing to the public 
release notes for MarkLogic Server 3.2 at 
http://developer.marklogic.com/pubs/3.2/books/relnotes.pdf - if that 
doesn't help, perhaps you should try our support channels.
