Problem in replacing XML namespace using XSLT

[krish13]

Hello,

I need to just replace the XML namespace using XSLT. My input XML looks like as follows. I just want to replace "oldNameSpace" with "newNameSpace" and rest of XML want as it is..

<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
	xmlns:impl="oldNameSpace" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
	<soapenv:Body>
		<impl:requestData
			xmlns:impl="oldNameSpace">
			<xmlString ChangeDate="2008-12-18T14:47:11.773+01:00"
				IdentificationNumber="WDDKJ5GBXAF000229"
				OrderNumber="08 295 70821"
				ProductionNumber="1700158">
				<ServiceTool ExecutionTime="2008-12-18T14:47:11.773+01:00"
					UserID="kris" Version="1.1.1" />
			</xmlString>
		</impl:requestData>
	</soapenv:Body>
</soapenv:Envelope>

I tried with following XSL

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
	xmlns:source="oldNameSpace"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="1.0"  >
	<xsl:output method="xml" encoding="iso-8859-1" indent="yes"       />
 
	<xsl:template match="source:*"   >
		<xsl:element name="{name(.)}" namespace="newNameSPace">
		<xsl:copy >
			<xsl:copy-of select="@*"   />
			</xsl:copy>
			<xsl:apply-templates />
		</xsl:element>
	</xsl:template>
 
	<!-- Just copy any other elements, attributes, etc. -->
	<xsl:template match="@*|node()">
		<xsl:copy   >
			<xsl:apply-templates select="@*|node()" />
		</xsl:copy>
	</xsl:template>
</xsl:stylesheet>

but it is not giving the desired results...it is giving the following results.

<?xml version="1.0" encoding="iso-8859-1"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:impl="oldNameSpace" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
	<soapenv:Body>
		<impl:requestData xmlns:impl="newNameSPace">
<impl:requestData xmlns:impl="oldNameSpace"/>
			<xmlString xmlns:impl="oldNameSpace" ChangeDate="2008-12-18T14:47:11.773+01:00" IdentificationNumber="WDDKJ5GBXAF000229" OrderNumber="08 295 70821" ProductionNumber="1700158">
				<ServiceTool ExecutionTime="2008-12-18T14:47:11.773+01:00" UserID="kris" Version="1.1.1"/>
			</xmlString>
		</impl:requestData>
	</soapenv:Body>
</soapenv:Envelope>

Anyone can help in this ....
Thanks a lot.

There is no simple way to do what you want using XSLT because of the multiple namespace declarations in the root element. In fact, the simpliest way is to use a stream editor such as sed.

However, if you are willing to accept a slight modification of the file to eliminate redundant namespace declarations, try the following stylesheet

<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
   xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope"
   xmlns:xsl="http://www.w3.org/1999/XSL/Transform" >

  <xsl:output method="xml" encoding="UTF-8" indent="yes" />

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

  <xsl:template match="node()[name() = 'soapenv:Envelope']" >
     <xsl:element name="{name(.)}">
        <xsl:apply-templates select="@*|node()"/>
     </xsl:element>
  </xsl:template>

  <xsl:template match="node()[starts-with(name(),'impl:')]">
     <xsl:element name="{name(.)}" namespace="newNameSpace">
       <xsl:apply-templates select="@*|node()"/>
     </xsl:element>
  </xsl:template>

</xsl:stylesheet>

This outputs

<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope">
        <soapenv:Body xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
                <impl:requestData xmlns:impl="newNameSpace">
                        <xmlString ChangeDate="2008-12-18T14:47:11.773+01:00" IdentificationNumber="WDDKJ5GBXAF000229" OrderNumber="08 295 70821" ProductionNumber="1700158">
                                <ServiceTool ExecutionTime="2008-12-18T14:47:11.773+01:00" UserID="kris" Version="1.1.1"/>
                        </xmlString>
                </impl:requestData>
        </soapenv:Body>
</soapenv:Envelope>
