RE: [xsl] RE: unwanted and non prefix namespaces in output

["Joel Friedman" <jfriedman@xxxxxxxxxxxx>]

Michael,

Thanks, that did fix the problem.  Out of curiosity (strictly academic
as my stylesheet does what I need it to), is there a more elegant
solution to the problem?  Or is the stylesheet I wrote along the correct
lines?

Thanks,

--Joel

I don't know what XSLT processor you're using, but the output I'm seeing
from Saxon (which I believe is correct) starts:

<sequence xmlns:ads="http://schemas.microsoft.com/ads/2003/sequence";
version="1" description="foo" command="bar">

   <sequence version="1" description="Image" command="WIN2000">

      <task xmlns="http://schemas.microsoft.com/ads/2003/sequence";>

The first <sequence> element is generated from a literal result element
in your stylesheet. It is in no namespace because the stylesheet doesn't
put it in a namespace. It copies the declaration of xmlns:ads from the
stylesheet because that's what literal result elements do.

The second <sequence> element is the same, but it doesn't redeclare
xmlns:ads because that would be redundant.

The <task> element is generated by copying from the source document. The
element is in the ads/2003 namespace because it stays in the same
namespace when you copy it. The original <task> element has an in-scope
namespace with prefix "" and uri "http://....ads/2003/...";, so the
copied element has one too.

I think, if I understand your problem description, that you probably
want to write <xsl:copy> where you currently write <sequence>. That way
you will get the namespaces that are in scope for the source element,
not those that are in scope in the stylesheet.

You made a lot of headway in four hours...
