If it's XHTML then it's in a namespace, which means it isn't called
"textarea" but "xhtml:textarea".

Subject: [xsl] CDATA or escape in the result tree problems
Hi all!
I'm trying to integrate TinyMCE, a JavaScript WYSIWYG editor,
into my system. TinyMCE produces XHTML, and can be attached
to textareas.
Textareas in HTML cannot contain other HTML elements, thus
the problem arises that the HTML needs to be escaped or put
into a CDATA section.
At first, I thought this was going to be a straightforward
application of cdata-section-elements="textarea", and that is
also what is indicated in the FAQ. It does not work as
expected, however.
I use Perl's XML::LibXSLT, which uses GNOME's libxslt.
My test system is Ubuntu Dapper, with the versions 1.58-1 and
1.1.15 respectively. My production system is Debian Sarge,
with somewhat older libraries. I haven't tested there yet.
It may influence the situation that I have a stylesheet with
the following output element:
<xsl:output version="1.0" encoding="utf-8" indent="yes"
method="html" media-type="text/html"
doctype-public="-//W3C//DTD HTML 4.01//EN"
doctype-system="http://www.w3.org/TR/html4/strict.dtd";
cdata-section-elements="textarea"
/>
which imports a stylesheet match-control.xsl that contains
<textarea name="{(_at_)name}" id="{(_at_)name}"
rows="{(_at_)rows}" cols="{(_at_)cols}">
<xsl:copy-of select="./ct:value/*/*"/>
</textarea>
This outputs HTML, not wrapped in a CDATA, nor escaped. If I
run the resulting code through the W3C HTML validator, it
complains that it is invalid. I'd like the resulting nodes of
<xsl:copy-of select="./ct:value/*/*"/> put into a CDATA
section, or perhaps escaped.
Any ideas why this is so? Is it because I import this
stylesheet? Is it a weakness with libxslt? Or have I
misunderstood cdata-section-elements?
Now, I assume that a CDATA section is The Right Way To Do It,
but I don't know if TinyMCE thinks likewise. I have seen it
simply escape < and > to < and >, and still submit it
back as proper HTML.
So, I figured, maybe I should be more pragmatic about it (I'm
normally such a purist), and just escape them too...
The problem is that I allow users to insert pretty much any
HTML in there. My application does some validation and a bit
of cleanup, so it should be valid, but that makes is slightly
harder to write the template that it should match on if I
were to just escape the HTML. If the cdata thing above seems
hard to do, I would be happy for advices on how to do this as well.
Cheers,
Kjetil
