Status: RESOLVED INVALID

(Firefox :: General, defect)

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.6) Gecko/20050225 Firefox/1.0.1

Although JavaScript works on XHTML served as XML, but labeled as XHTML by both
DOCTYPE and HTTP-EQUIV, in that the DOM is correctly manipulated, elements
created are rendered as no-ops. In this instance, the <em> created might as well
be <span>.

If running locally, the JS works when the file is named *.xhtml and fails when
it is named *.xml.

Reproducible: Always

This bug may be invalid. AFAIK you have to use document.createElementNS()
instead of document.createElement() when manipulating the DOM of XML (including
XHTML, SVG, etc.) documents. I'm not absolutely sure about this, though. Leaving
as "unconfirmed" for the moment...

Comment 2

[John W. Kennedy]

If so, there is a curious inconsistency, because A) the very same, byte-for-byte
identical documents work when they are served as "application/xml+xhtml", and B)
everything /except/ JavaScript works fine when XHTML is served as "text/xml".

(Unfortunately, the webserver I am using, over which I have no control, serves
*.xhtml as text/plain, but serves *.xml as text/xml.)

Behavior is persistent in the latest nightly.  However, I agree with comment 1
about the validity of this bug.  The behavior when not using createElementNS is
undefined, so quirky behavior can be expected.  Marking as INVALID.
