RE: Temporary tree elements and namespaces: Further q

Hi all, [xsl 1.0, processor .NET XslTransform]

I read this thread with interest and it helps me a great deal but not
completely. I'm bringing in another document. My transform is from xhtml to
xhtml so I have the following declarations (including default declaration
for xhtml):

<xsl:stylesheet 	version="1.0" 
			xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
			xmlns:xhtml="http://www.w3.org/1999/xhtml" 
			xmlns="http://www.w3.org/1999/xhtml" 
			exclude-result-prefixes="xhtml">

I then load a reference document map.map (with no internal namespace) to
relate pairs of files together in links. It contains:
	<mappings>
		<relationship topic="1561.htm" toc="toc9497.htm" />
		<relationship topic="950.htm" toc="toc.htm" />
		.
		.
	</mappings>

Which I load into a variable as follows:

	<xsl:variable name="mappings"
select="document('map.map')/mappings/relationship" />

Which I'm assuming loads _all_ the relationships into $mappings.

The next step is to recognise the @href in the source document for, for
instance, 1561.htm (as shown above) and use it to look up the corresponding
filename toc9497.htm. This doesn't go well because I don't have separate
namespaces:

	<xsl:value-of select="$mappings/relationship[@topic=@href]/@toc">

Where @href is in the default xhtml namespace and @topic and @toc are in the
new namespace.

The question is, where do I declare the new namespace and how do I ensure it
is applied to the relationships and attributes in map.map?

Thanks again,
Richard
