[XSLT] How to generate /<![CDATA[/ for XHTML style element?

06-16-2006

I'd like to generate something like that:

<style type="text/css">/*<![CDATA[*/
body { }
*/]]></style>

I thought the following would work, but it doesn't (I tried with
xsltproc).

<?xml version="1.0"?>

<xsl:stylesheet version="1.0"
xmlns

sl="http://www.w3.org/1999/XSL/Transform"
xmlns="http://www.w3.org/1999/xhtml">

<xsl

utput method="xml"
encoding="iso-8859-1"
doctype-public="-//W3C//DTD XHTML 1.0 Strict//EN"
doctype-system="http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"
indent="yes"/>

<xsl:template match="/">
<html>
<head>
<title>.</title>
<style type="text/css">
<xsl:text disable-output-escaping="yes">/*<![CDATA[*/
body { }
/*]]>*/</xsl:text>
</style>
</head>
<body><p>.</p></body>
</html>
</xsl:template>

</xsl:stylesheet>

Any idea?

This construct is useful only if the stylesheet contains "]]>", "&", or
"<" and you want both HTML tag soup and XML processors to successfully
process the document; if that is ever the case you should use external
style sheets instead, or, if possible, escape the characters using
\hhhhhh escapes instead.

Or for better maintainability, e.g. if the styles are incomplete and
one wants to make sure not to forget to add this construct when the
styles get "&" or "<" characters in future modifications.

This is the best solution when the page is on a web server, but in
other cases, e.g. when one wants to distribute a HTML file by e-mail,
internal styles may be an easier solution.

But this is less readable and also more prone to bugs when generating
styles from a programming language where \ is the escape character.

You can tell XSLT that the text children of certain elements should be
escaped as CDATA Sections, via the cdata-section-elements attribute of
the xsl

utput directive.

I agree that this is generally something you should avoid, but if the
customer/boss insists on it...

That would not work here as the CDATA section delimiters have to be
surrounded by /* ... */ comment delimiters.

Why does <style> have to be a CDATA section anyway? (ignoring the
bogosity of the /* <![CDATA[ ... ]]> */ construction)

<script> has some arguments for it, in some particular circumstances,
but <style> doesn't.

In that case, assembling it out of characters -- and outputting through
a path which suppresses normal XML escaping -- may indeed be the best
you can do. Or you can perform non-XML-based postprocessing to replace
the <![CDATA[]]> delimiters with their Javascript-commented-out equivalents.

The better answer remains: Don't Do That. The whole point of XHTML is
that it is XML-based, and that *should* mean you don't have to kluge
using <![CDATA[]]> and comments to make it accept scripts. If that isn't
true, beat up the browser authors until they fix their code.

It's no an XHTML problem, it's a problem for appendix C XHTML which is
being fed to SGML parsers and expected to work transparently as
_either_ XML or SGML, from the same document. The addition of the
comment markers is a particularly obsessive case. Hixie is obsessed
with this, no-one else really cares.
