Stripping namespace from a particular element in soap message - xslt

Question

MY requirement is to get expected output from the input message using xslt .
The xslt which i am using has been provided for review..
Input message :
<soapenv:Envelope xmlns:v2="http://service..com/esbd/customer/customerlookup/v2"
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:v1="http://schema..com/esbd//esbSubHeader/v1">
<soapenv:Header>
<wsse:Security xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd"
soapenv:mustUnderstand="0">
<wsse:UsernameToken>
<wsse:Username></wsse:Username>
<wsse:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText">
1</wsse:Password>
</wsse:UsernameToken>
</wsse:Security>
**<base:TrackingInfo xmlns:base="http://base.canonical.something.com/">

<arg0>
<BirthDttm />
</arg0>
</web:lookUpCustomer>
</soapenv:Body>
</soapenv:Envelope>
expected output :
<soapenv:Envelope xmlns:v1="http://schema.something.com/esbd/esbSubHeader/v1"
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:v2="http://service.something.com/esbd/customer/customerlookup/v2">

<arg0>

</arg0>
</web:lookUpCustomer>
</soapenv:Body>
</soapenv:Envelope>
i am trying to get the output using the below xslt
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:base=""http://base.canonical.something.com/""
xmlns:v2="http://service.something.com/esbd/owg/customer/customerlookup/v2"
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:v1="http://schema.something.com/esbd/owg/esbSubHeader/v1"
exclude-result-prefixes="base v2 v1">
<xsl:output omit-xml-declaration="yes" indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:template match="node()|#*">
<xsl:copy>
<xsl:apply-templates select="node()|#*"/>
</xsl:copy>
</xsl:template>
<xsl:template match="base:*">
<xsl:element name="{local-name()}">
<xsl:copy-of select="namespace::*[not(. = namespace-uri(..))]"/>
<xsl:apply-templates />
</xsl:element>
</xsl:template>
</xsl:stylesheet>
but instead of getting expected output getting below O/P message
<soapenv:Envelope xmlns:v1="http://schema.something.com/esbd/esbSubHeader/v1"
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:v2="http://service.something.com/esbd/customer/customerlookup/v2">

<wsse:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText">

</wsse:UsernameToken>
</wsse:Security>
**<TrackingInfo>

Could anybody please help me out where exactly i am going wrong ....

Answer 1

In your XML, the prefix base is bound to URI:
"http://base.canonical.something.com/"
Your stylesheet binds it to:
"http://base.canonical.owg.walgreens.com/"
For this reason, the template:
<xsl:template match="base:*">
matches nothing and the default identity transform template is applied to elements whose name starts with the base prefix.
Once you fix that, you should be getting the expected output. Note that the instruction:
<xsl:copy-of select="namespace::*[not(. = namespace-uri(..))]"/>
is unnecessary.
Note also that:
<ApplicationId xmlns:base="http://base.canonical.something.com/">BMW</ApplicationId>
is exactly the same thing as:
<ApplicationId>BMW</ApplicationId>
If you are bothered about the redundant namespace declaration (which only some processors will copy from the original), add one more template to your stylesheet:
<xsl:template match="*[not(namespace-uri())]">
<xsl:element name="{name()}">
<xsl:apply-templates />
</xsl:element>
</xsl:template>
or extend the existing one to:
<xsl:template match="base:* | *[not(namespace-uri())]">
<xsl:element name="{local-name()}">
<xsl:apply-templates />
</xsl:element>
</xsl:template>
But all of this is just cosmetics: the resulting XML is semantically the same as the one received without making these changes.
