Please don't go off-list.
>But these

I'm not arguing about
whether your design approach is reasonable, I'm just telling you it won't work,
because XSLT etc can't handle non-XML documents.
>Be another approach

So long as you know
that namespace prefixes are used only in element and attribute names, you can
eliminate unused namespaces with the simple XSLT 2.0
instruction
<xsl:copy-of
select="/" copy-namespaces="no"/>
One downside is that
namespaces that are used will only be declared at the level where they are used,
which may lead to repeated declarations.

Thanks,
But these
document-fragment are userinput, which will be put together in one document.
The users mostly won’t provide the namespace and therefore I’d like to add
them ‘myself’.
Be another approach
would be the other way around, I’ll add all the namespaces that are known and
then filter out the unused ones (to prevent overhead). The namespaces could be
more than 20, but sometimes only 5 are used, that’s why I’d like to make the
final check and strip unnecessary namespace
declarations.

prefixes from a XML document
If your document
contains undeclared prefixes, then not only is it incomplete, but for all
practical purposes it isn't an XML document. Which means you won't be able to
process it using XPath, XSLT, or XQuery.

Subject: [xml-dev] Get all unique
prefixes from a XML document
Hello,
I’ve created a XML document, but
it isn’t complete, because I’ll still need to add the namespace declarations
on top when the document is ready. Therefore I’d like to use XPath to get
all prefixes, and based on that prefixes, add the namespaces. It’s not 100%
correct to use fixed prefixes, I know, but it’ll solve my problem. I’ve been
trying to do something with namespace-uri() finding the unique ones, but it
didn’t work out. Can someone help me creating the right
query?
//*[
not( namespace-uri() = namespace-uri(preceding-sibling::node())
) ]
Thanks in
advance,
