[webkit-help] XSLTProcessor: transformToFragment returns HTMLElement even with method="xml"

[Gregoire]

Hi again,

I've created a test-case so that it is easier to answer my question.

The included files are a XForms application. So, for this test-case to
work, you need to download XSLTForms from the "XML Data Island" branch,
with the following svn command:

svn -r 448 co
https://xsltforms.svn.sourceforge.net/svnroot/xsltforms/branches/dataisland
xsltforms-data-island-448

Put the attached files "test-chrome-xslt.xml" and "test-chrome-xslt.js"
in the directory containing the "xsltforms-data-island-448" directory.
Then open the file in both Firefox and in a WebKit based browser (it
seems necessary to open the file through a local web server with WebKit,
otherwise you get a blank white screen).

In the debugger, add a watch expression on
"myInstance.childNodes[0].childNodes", and put a breakpoint on line 12
of "test-chrome-xslt.js".

Then click in the drop-down menu. You will see:
0:Element
1:Element
2:Element
3:Element
4:Element
which is normal because it is before the sorting.

After a second click in the drop-down menu, you will see:
0:Element
1:HTMLElement
2:HTMLElement
3:HTMLElement
4:HTMLElement

And then everything will disappear because "transformToFragment" (line
20) doesn't seem able to work with "HTMLElement"s.

If this is a bug, please tell me and I will fill a bug report.

Regards,
Gregoire
