RE: [xsl] Do a copy of a document but avoid duplicates in ce

Hei David,

yes, yes I was aware of all these things ... 
I thought it would be reasonable to assume that an unqualified 
element name in an xpath expression would automatically belong to the 
default namespace in the source document 
because you can't create to many aliases like "a" "b" 
with the empty String "" ;-)).

But you are right I could somewhere done in my source document tree 
again overwrite the default namespace (uri) and that would really create 
astonishing results with such a default mechanism. 
(And of course the elements from the null namespace...)

Thanks
Case completely closed.
Georg

It isn't a fake namespace node it is an essential part of the name.
A name consists of two parts a local name "html" "ul" etc and a
namespace, "http://www.w3.org/1999/xhtml"; If you mis out the namespace
in your Xpath it doesn't match, just as if you missed out a leter of the
local name.

>  from the default name space?!?!
Which prefix is used in the source document (or if no prefix is used at all)
has _no effect_ at all on the Xpaths used to match the elements.
The XML Namespace recommensation stresses that
<html xmlns="http://www.w3.org/1999/xhtml";>
<a:html xmlns:a="http://www.w3.org/1999/xhtml";>
<b:html xmlns:b="http://www.w3.org/1999/xhtml";>

are all the same thing and so you would not want Xpaths to work with the
first one but not the second two.

similarly 

<html>

is a different element, html in the null namespace, and that is the
element your Xpaths are matching.
