msxsl:node-set with default namespace

[MoonStorm]

Hi guys,

Please solve a puzzle I am trying to figure out for some time.
Let's say I have a fragment stored inside a variable, for instance:

<xsl:variable name="layoutSettings">
<module>
<size>345</size>
<title>whatever</title>
</module>
</xsl:variable>

My standard namespaces look like this:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:msxsl="urn:schemas-microsoft-com:xslt">

The node-set function behaves as expected.
The trouble appears when I try to add a default namespace to the
xsl:stylesheet declaration. A
select="msxsl:node-set($moduleSettings)/module/size" will return
nothing.

This behaviour is nothing to do with node-set() you will see the same
behaviour if you add a namespace to a source document. unprefixed
element names in XPath 1 _always_ refer to elements in no-namespace.

By adding a default namespace the elements in your variable are now in
that namespace.

Either you have to prefix the names in the Xpath or add xmlns="" to the
xsl:variable so the elements within it are in no-namespace.

Yes, you are right. Now it works.

However, from what I understand and tested, I cannot prefix the names in
xpath with the default namespace. If I choose this option, I have to
declare a new namespace and include the elements in that namespace. Am I
right?

you need to declare the same namespace twice with and without a prefix

<xsl:stylesheet xmlns="wibble" xmlns="w:wibble" ....

Now a literal result element of
<foo> is foo in wibble namepsace (as is <w:foo> ) and an Xpath of
//x:foo will find foo in the wibble namespace (whether or not it was
prefixed in the source)

Brrrrr, yes, it works. Thanks a lot.
Hopefully the standard will evolve in a more friendly way.

Yes it will, XSLT2 draft (which is already implemented in, eg, saxon8.x)
allows you to specify a default namespace for element names in Xpath
expressions, so you could keep everything unprefixed, and just use the
default namespace, then also declare that unprefixed xpath names refer
to that.
