Re: Re: Re: Removing namespaces from source document (

I don't think it is a good idea to strip elements of all namespaces
they don't immediately use. This ends up with re-defining the same
namespace over and over again on many different elements -- both
difficult to understand and to change/maintain.

For example, the following xml source:

<root xmlns:good-ns="http://good.com" xmlns:bad-ns="http://bad.com">
  <parent color="red">
   <good-ns:child shape="square">
    some text
    </good-ns:child>
  </parent>
  <parent color="blue">
   <good-ns:child shape="triangle">
    some text
    </good-ns:child>
  </parent>
  <parent color="green">
   <good-ns:child shape="circle">
    some text
    </good-ns:child>
  </parent>
</root>


will be transformed into:

<root>
  <parent color="red">
   <good-ns:child xmlns:good-ns="http://good.com" shape="square">
    some text
    </good-ns:child>
  </parent>
  <parent color="blue">
   <good-ns:child xmlns:good-ns="http://good.com" shape="triangle">
    some text
    </good-ns:child>
  </parent>
  <parent color="green">
   <good-ns:child xmlns:good-ns="http://good.com" shape="circle">
    some text
    </good-ns:child>
  </parent>
</root>

I was almost there...

This example still requires hard-coding of the specific namespaces that

aren't desired - in otherwords, it's a sort of blacklist filter.  It's
also 
possible to do this constructively:

<!-- For all elements: -->
<xsl:template match="*">
   <xsl:choose>

     <!-- If there is no prefix, and no default namespace in
          scope: -->
     <xsl:when test="substring-before(name(current()),':') = '' and
                     not(namespace::*[name() = ''])">

       <!-- Just create the element with no namespace. -->
       <xsl:element name="{name()}">
         <xsl:apply-templates select="node()|@*" />
         </xsl:element>
     </xsl:when>

     <!-- If there's no prefix, but there is a default namespace
          in scope: -->
     <xsl:when test="substring-before(name(current()),':') = ''">

       <!-- Make the element with the default namespace. -->
       <xsl:element name="{name()}" namespace="{namespace-uri(.)}">

         <!-- Copy the default namespace. -->
         <xsl:copy-of select="namespace::*[name*() = '']"/>
         <xsl:apply-templates select="node()|@*"/>
       </xsl:element>
     </xsl:when>

     <!-- But if there is a prefix, or a default namespace: -->
     <xsl:otherwise>

       <!-- Then create the element with the right namespace, -->
       <xsl:element name="{name()}" namespace="{namespace-uri(.)}">

         <!-- and copy the namespace actually used by this
              element. -->
         <xsl:copy-of
           select="namespace::*
                     [name() =
                        substring-before(name(current()),':')]"/>
         <xsl:apply-templates select="node()|@*" />
         </xsl:element>
     </xsl:otherwise>
   </xsl:choose>
</xsl:template>
