Question

I am using Microsoft’s XSLT processor (1.0 only)

XML opening lines:

<?xml version="1.0" encoding="utf-8"?>
<Header xmlns="http:\\OldNameSpace.com">
    <Detail>

Have the following XSLT template to pick up the <Header> element of my document and change its namespace.

<xsl:template match="*">
    <xsl:element name="{name()}" xmlns="http:\\NewNameSpace.com"> 
        <xsl:copy-of select="@*"/>
        <xsl:apply-templates />
    </xsl:element>
</xsl:template>

Which turns <Header xmlns="http:\\OldNameSpace.com"> Into <Header xmlns="http:\\NewNameSpace.com">

However I now need to add a second namespace to this so that I get the following output:

<Header xmlns="NewNameSpace.com" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

I have tried using:

<xsl:template match="*">
    <xsl:element name="{name()}" xmlns="NewNameSpace.com" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> 
        <xsl:copy-of select="@*"/>
        <xsl:apply-templates />
    </xsl:element>
</xsl:template>

However I still only get the same output as the original XSLT template.

Can anyone enlighten to me as to why this is?

This transformation:

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
 xmlns:old="http:\\OldNameSpace.com"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  exclude-result-prefixes="old xsi">
 <xsl:output omit-xml-declaration="yes" indent="yes"/>
 <xsl:strip-space elements="*"/>

 <xsl:param name="pNewNamespace" select="'http:\\NewNameSpace.com'"/>

 <xsl:variable name="vXsi" select="document('')/*/namespace::*[name()='xsi']"/>

 <xsl:template match="node()|@*">
     <xsl:copy>
       <xsl:apply-templates select="node()|@*"/>
     </xsl:copy>
 </xsl:template>

    <xsl:template match="old:*">
        <xsl:element name="{local-name()}" namespace="{$pNewNamespace}">
          <xsl:copy-of select="$vXsi"/>
            <xsl:copy-of select="@*"/>
            <xsl:apply-templates />
        </xsl:element>
    </xsl:template>
</xsl:stylesheet>

when applied on the following XML document:

<Header xmlns="http:\\OldNameSpace.com">
    <Detail/>
</Header>

produces (what I guess is) the wanted, correct result:

<Header xmlns="http:\\NewNameSpace.com"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
   <Detail/>
</Header>
