Re: How to remove namespace declarations and prefixes?
For the same problem I'm using this pure XSL solution
xsl:template match=* priority=-1 mode=copy
xsl:element name={name()}
xsl:copy-of select=@*/
xsl:apply-templates mode=copy/
/xsl:element
/xsl:template
xsl:template match=text() mode=copy
xsl:value-of select=normalize-space(.)/
/xsl:template
The weight on performance could be balanced by finer handling of nodes.

Subject: RE: How to remove namespace declarations and prefixes?
Hi Richard,
I also had this same problem. I did some reading, and according to
Michael
Kay's XSLT Programmer's Reference:
The xsl:exclude-result-prefixes and exclude-result-prefixes attributes
apply only to namespace nodes copied from the stylesheet using literal
result elements. They do not affect namespace nodes copied from the
source
document using xsl:copy or xsl:copy-of: there is no way of suppressing
these.
Unfortunately, since xslt's will often have a catch-all template matcher
to
copy elements it doesn't transform, this comes up quite a bit.
So... what I ended up doing was extending the HTMLSerializer (or whatever
serializer you're using for your pipelines), and overriding the
startPrefixMapping and endPrefixMapping methods to do nothing, effectively
removing all namespaces from my HTML. This also had the added benefit of
having no performance penalties (and theoretically, a ever-so-slight
speedup
since we no longer process namespaces in our serializer).
You could make this more general, and use the serializer's configuration
to
declare which namespaces you want to exclude, but excluding all worked
well
for us, especially since we were outputting HTML.
Hope that helps!
Harry

Thank you for this solution.
- Do you know if this influences the performance?
- Is there a special reason why exclude-result-prefixes
doesn't work or is it a bug?

Piece of cake. A stylesheet which does exactly that would is
?xml version=1.0 encoding=UTF-8?
xsl:stylesheet version=1.0
xmlns:xsl=http://www.w3.org/1999/XSL/Transform;
xsl:output method=xml version=1.0 encoding=UTF-8 indent=yes/
xsl:template match=*
!-- remove element prefix (if any) --
xsl:element name={local-name()}
!-- process attributes --
xsl:for-each select=@*
!-- remove attribute prefix (if any) --
xsl:attribute name={local-name()}
xsl:value-of select=./
/xsl:attribute
/xsl:for-each
xsl:apply-templates/
/xsl:element
/xsl:template
/xsl:stylesheet
However, adding another step in your pipeline may not be the best
solution. You might want to modify your existing last stylesheet to
remove prefixes using the local-name() function as above.
Hope this helps,
Manos

Reinhard, *anything* influences performance. The professor at the course
I follow, presented this issue very simply as In software design, you
always give some to take some.
- Is there a special reason why exclude-result-prefixes
doesn't work or is it a bug?
Are you using it correctly?
For example, if you know your XSLT will *only* process either XSD or
XHTML documents, you can do the same with
?xml version=1.0 encoding=UTF-8?
xsl:stylesheet version=1.0
xmlns:xsl=http://www.w3.org/1999/XSL/Transform;
xmlns:xs=http://www.w3.org/2001/XMLSchema;
xmlns:xht=http://www.w3.org/1999/xhtml;
exclude-result-prefixes=xs xht
xsl:output method=xml version=1.0 encoding=UTF-8 indent=yes/
xsl:template match=*|@*
xsl:copy
xsl:apply-templates/
/xsl:copy
/xsl:template
/xsl:stylesheet
Note that you have to declare ALL the namespaces you wish to filter out
by associate them with a namespace prefix(duh); then put a space
separated list of ALL prefixes as the value of the
exclude-result-prefixes attribute.
The only case this doesn't work is when you don't know the namespaces
you may encounter.
Cheers,
Manos

Reinhard
