add namespace + prefix to XML using XSL

I hope you can help... Let's assume I have following XML:

<data>
   <token>
      <sessionId>12345</sessionId>         
      <userId>john</userId>
      <moreInfo>
         <bla> .....
         </bla>
      </moreInfo>
   </token>
</data>

And I need this to become

<login:data xmlns:login="http://my.ns.uri">
       <login:token>
          <login:sessionId>12345</sessionId>         
          <login:userId>john</userId>
          <login:moreInfo>
             <login:bla> .....
             </login:bla>
          </login:moreInfo>
       </login:token>
    </login:data>

Can I do this with XSL? I did try but failed miserably ... Any help would be greatly appreciated!

Thanks, Jan

XSLT 2.0 is more efficient and compact. It supports to add namespaces to node directly. We don't need to define anything in the starting of stylesheet as well.

Here is the spec : creating namespace prefix

Use :

<xsl:stylesheet version="2.0"
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output omit-xml-declaration="yes" indent="yes"/>
 <xsl:template match="*">
  <xsl:element name="login:{name()}" xmlns:login="http://my.ns.uri">
   <xsl:namespace name="login">http://my.ns.uri</xsl:namespace>
   <xsl:value-of select="node()"/>
   <xsl:apply-templates select="*"/>
  </xsl:element>
 </xsl:template>
</xsl:stylesheet>

It will give the output :

<login:data xmlns:login="http://my.ns.uri">
   <login:token>
      <login:sessionId>12345</login:sessionId>
      <login:userId>john</login:userId>
      <login:moreInfo>
         <login:bla> .....
         </login:bla>
      </login:moreInfo>
   </login:token>
</login:data>

Use:

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
 xmlns:login="http://my.ns.uri">
 <xsl:output omit-xml-declaration="yes" indent="yes"/>

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

 <xsl:template match="*">
  <xsl:element name="login:{name()}" namespace="http://my.ns.uri">
    <xsl:copy-of select="namespace::*"/>
    <xsl:apply-templates select="node()|@*"/>
  </xsl:element>
 </xsl:template>
</xsl:stylesheet>

When this transformation is applied on the provided XML document, the wanted, correct result is produced:

<login:data xmlns:login="http://my.ns.uri">
   <login:token>
      <login:sessionId>12345</login:sessionId>
      <login:userId>john</login:userId>
      <login:moreInfo>
         <login:bla> .....
         </login:bla>
      </login:moreInfo>
   </login:token>
</login:data>

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