275745 - Use of xsl:output with method="xml" rendered as plain text

Status: RESOLVED INVALID

(Core :: XSLT, defect)

Description

[Jamie Thompson]

Note: I wasn't sure which category to file this in, as I'm using FireFox and not
 SeaMonkey, and Firefox doesn't have a XSLT category...anyway...

If I specifiy the xsl:output tag in my stylesheet with method="html" all is well
aside from the fact that mozilla renders in html mode. I am using xhtml and
would like to use that rendering mode, but if I specify method="xml" then the
output I get is plain text.

Ideally I would like to be using something like:
<xsl:output
	method="xml"
	encoding="iso-8859-1"
	indent="yes"
	doctype-public="-//W3C//DTD XHTML 1.0 Transitional//EN"
	doctype-system="http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"
/>

...but alas, this isn't going to be possible whilst this bug lives. As a side
note, renders fine in IE6...though going from my experiments tonight thats more
due to blissful ignorance than anything else.

I've posted testcases here, they're identical aside from the xsl:ouput elements:
http://random.jamie-thompson.co.uk/wibble.xml (method="xml")
http://random.jamie-thompson.co.uk/wibble2.xml (method="html")

Seamonkey doesn't have an XSLT component anymore either: Core, which we share, does.

First off, i'd recommend that you use method="html" rather then method="xml" if
your creating a cross-browser xslt stylesheet. The reason is that IE doesn't
support xhtml (or indeed method="xml") so you'll end up with html there wheather
you like it or not.

If you still want to use xhtml in mozilla you need to create the new elements in
the right namespace, otherwise we won't recognize it as xhtml. Add the following
attribute to the xsl:stylesheet element:

xmlns="http://www.w3.org/1999/xhtml"

My apoligies. In all the references I used, none mentioned the modification of
the stylesheet element, and it never would have occurred to me to have two
namespace attributes in it, as I was under the assumption that the stylesheet
required the xsl namespace as that's what it was. The IE issue isn't, it renders
appropriately, but I aim for standards compliance, then add workarounds for
bad/old implementations, I find that it's better maitenence-wise in the long run.

Again, cheers for your help, and sorry for wasting your time.

IE renders it as html, not xhtml. The differences in rendering are very small
though, but they are there. Also the DOM of html and xhtml have quite a few
differences. Basically you are bound to run into these differences sooner or later.

xhtml is no more "standards complience" then html is. The choise is yours of course.
