carrying xml name spaces across nested elements

[Datawich]

Hi. By persistence, I've discovered that when several nested elements
in a schema are each qualified by a namespace, I can successfully
reference them in a select statement by qualifying each element by its
namespace in succession. For example, for a schema that qualfies each
element in a nested series "command, heading, pivot table" by "xs", I
can use an xpath statement like "//xs:command/xs:heading/
xs:pivotTable" to select the pivot table node.

I figure that when all the name space qualifications are identical,
there's some way to carry the namespace across all the elements
without typing exact same one for each separately. Is there? If so,
could someone tell me what it is?

Thanks for any help!

With XSLT 2.0 and XPath 2.0 there is an XPath default namespace that you
can set e.g.
<xsl:styleshe et
xmlns:xsl="http ://www.w3.org/1999/XSL/Transform"
version="2.0"
xpath-default-namespace="http ://example.com/2008/ns1">

<xsl:template match="/">
<xsl:value-of select="//command/heading/pivotTable"/>
so that way you don't need a prefix.

Is that what you have in mind, avoiding to type the prefix 'xs'?

XSLT and XPath 2.0 are not supported by Microsoft products but there are
third party implementations , Saxon from
<URL:http://saxon.sourcefor ge.net/has a .NET and a Java version,
AltovaXML <URL:http://www.altova.com/altovaxml.htmli s a COM solution,
Gestalt <URL:http://gestalt.sourcef orge.net/has binaries for different
platforms.
