template adds unexpected namespace

[Rolf Kemper]

Dear Experts,

I'm going to create an Excell spreadsheet xml. So far things work very
well. But in case I add <Row> elements by a recursive template call it
goes wrong.

See the attached XSLT and the result. Last 30 lines of the xslt may be
the most interesting ones. I'm processing it with XMLSPY. Regardless
of the xslt processor (ALTOVA / MSXML4 ) I get the same result.

Hence, I belive I have not done it right. Sorry for the long code, but
I do not really know where the problem might be.

Any help is welcome
Regards
Rolf

[David Carlisle]

<Row> <!-- here namespace xmlns="" is added as attribute
WHY ??? -->

Because at that point in the stylesheet the default namespace is
no-namespace so
<Row>
constructs an element with local name Row and namespace URI ""

But in the result tree the parent element has a namespace of

xmlns="urn:schemas-microsoft-comffice:spreadsheet"

so XSLT has to add xmlns="" to the start tag to keep Row in
no-namespace.

Solution, add

xmlns="urn:schemas-microsoft-comffice:spreadsheet"
to the current <Row> tag in teh stylesheet or more simply just move all
the namespace declarations that you want in the result xsl:stylesheet
element so that they are in scopr for your whole stylesheet ie move them
from
here:
<Workbook xmlns="urn:schemas-microsoft-comffice:spreadsheet"
xmlns="urn:schemas-microsoft-comfficeffice"
xmlns:x="urn:schemas-microsoft-comffice:excel"
xmlns:ss="urn:schemas-microsoft-comffice:spreadsheet"


which means they are only in scope inside the template for "/".
