[xsl] Using XSLT as a namespace filter...

Greetings,

I have an application in which I want to pass only elements in a  
document that are members of a particular namespace. I want the  
elements, the attributes and text nodes, but no child elements or  
attributes from other namespaces.
Naively I though that I could just do something like this:


<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0"
               xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
               xmlns:dap="http://xml.opendap.org/ns/DAP2";

       >
   <xsl:output method='xml' version='1.0' encoding='UTF-8'  
indent='yes'/>
   <xsl:template match="/dap:Dataset">
       <xsl:copy >
           <xsl:apply-templates />
       </xsl:copy>
   </xsl:template>

   <xsl:template match="dap:*">
       <xsl:copy >
           <xsl:copy-of select="dap:*" />
       </xsl:copy>
   </xsl:template>

   <xsl:template match="*">
       <xsl:apply-templates />
   </xsl:template>

   <xsl:template match="text()|@*">
           <xsl:copy-of select="." />
   </xsl:template>

</xsl:stylesheet>

But all of the text content of the elements from other namespaces  
leaks through.
I realize that this guy:

   <xsl:template match="text()|@*">
           <xsl:copy-of select="." />
   </xsl:template>

Is the culprit.

After many futile attempts at trying write an XPATH to match only text  
and attributes whose parent element is in the dap namespace I am here,  
looking for some advice.

Any ideas? I have this feeling that the solution to this should be  
really simple, and that my transform is already twice as long as it  
should be.
