XSL - copy elements but remove unused namespace(s)

Question

I\'ve got some XML which declares a namespace which is only used for attributes, like this:

Answer 1

This will remove the x namespace from output.

<xsl:namespace-alias result-prefix="#default" stylesheet-prefix="x" />

Remember to do two things when you deal with a default namespace. First map it into something in the stylesheet tag, and then remove it using a namespace-alias.

Answer 2

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

  <!-- the identity template copies everything 1:1 -->
  <xsl:template match="@* | node()">
     <xsl:copy>
      <xsl:apply-templates select="@* | node()" />
    </xsl:copy>
  </xsl:template>

  <!-- this template explicitly cares for namespace'd attributes -->
  <xsl:template match="@x:*">
    <xsl:attribute name="{local-name()}">
      <xsl:value-of select="." />
    </xsl:attribute>
  </xsl:template>

</xsl:stylesheet>

Answer 3

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"
    xmlns:x="http://tempuri.com">
    <xsl:template match="/">
        <xsl:apply-templates select="/a/b"/>
    </xsl:template>

    <xsl:template match="*">
        <xsl:element name="{local-name(.)}">
            <xsl:apply-templates/>
        </xsl:element>
    </xsl:template>

    <xsl:template match="@*">
        <xsl:copy/>
    </xsl:template>

    <!-- This empty template is not needed.
Neither is the xmlns declaration above:
    <xsl:template match="@x:*"/> -->
</xsl:stylesheet>

I found an explanation here.

exclude-result-prefixes only affects the namespaces copied from the stylesheet by a literal result element, it doesn't affect copying of namespaces from source documents.

Answer 4

Try this (note the attribute copy-namespaces='no'):

<xsl:template match="node()">
    <xsl:copy copy-namespaces="no">
            <xsl:apply-templates select="node()"/>
    </xsl:copy>
</xsl:template>
