How to rename the existing namespace with new namespace in wso2esb - xpath

Question

I am using wso2esb-4.8.1,
I wish to change my request and response before sending to endpoint and client
so my request is
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<soapenv:Header xmlns:env="http://eai.ttt.pp.hh" xmlns:open="http://www.oly.org/" xmlns:xsi="xsi">
<pr:authentication soapenv:her="http://schemas.xmlsoap.org/soap/her/next" soapenv:mustUnderstand="0" xmlns:pr="http://webservices.temp.com/ProxyService">
<pr:user>sec5</pr:user>
<pr:password>ss</pr:password>
</pr:authentication>
</soapenv:Header>
<soapenv:Body>
<open:clientRequest xmlns:open="http://www.oly.org/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<env:EaiEnvelope xmlns:env="http://eai.ttt.pp.hh">
<env:Language>en</env:Language>
<env:UserId>admc</env:UserId>
<env:Payload>
<ss:security xmlns:ss="http://eai.admc.kyt/security">
<ss:Request>
<ss:Operation_Name>securityrem</ss:Operation_Name>
<ss:customerID>
<ss:no>9875452</ss:no>
<ss:Service_Type>gsm</ss:Service_Type>
</ss:customerID>
<ss:customer>
<ss:isCredit>false</ss:isCredit>
<ss:Amount>100000</ss:Amount>
<ss:transaction_Id>4301298</ss:transaction_Id>
<ss:TransactionTypeID>228</ss:TransactionTypeID>
<!--<ss:DeductionPriorityCode>2</ss:DeductionPriorityCode>-->
</ss:customer>
</ss:Request>
</ss:security>
</env:Payload>
</env:EaiEnvelope>
</open:clientRequest>
</soapenv:Body>
</soapenv:Envelope>
I wish to change the ss:security element namespace with xmlns:emp="http://uri.open.gen/com" so my request should be change as per new Namespace its lke this
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<soapenv:Header xmlns:env="http://eai.ttt.pp.hh" xmlns:open="http://www.oly.org/" xmlns:xsi="xsi">
<pr:authentication soapenv:her="http://schemas.xmlsoap.org/soap/her/next" soapenv:mustUnderstand="0" xmlns:pr="http://webservices.temp.com/ProxyService">
<pr:user>sec5</pr:user>
<pr:paempword>emp</pr:paempword>
</pr:authentication>
</soapenv:Header>
<soapenv:Body>
<open:clientRequest xmlns:open="http://www.oly.org/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<env:EaiEnvelope xmlns:env="http://eai.ttt.pp.hh">
<env:Language>en</env:Language>
<env:UserId>admc</env:UserId>
<env:Payload>
<emp:safety xmlns:emp="http://uri.open.gen/com">
<emp:Request>
<emp:Operation_Name>securityrem</emp:Operation_Name>
<emp:customerID>
<emp:no>9875452</emp:no>
<emp:Service_Type>gsm</emp:Service_Type>
</emp:customerID>
<emp:customer>
<emp:isCredit>false</emp:isCredit>
<emp:Amount>100000</emp:Amount>
<emp:transaction_Id>4301298</emp:transaction_Id>
<emp:TransactionTypeID>228</emp:TransactionTypeID>
<!--<emp:DeductionPriorityCode>2</emp:DeductionPriorityCode>-->
</emp:customer>
</emp:Request>
</emp:safety>
</env:Payload>
</env:EaiEnvelope>
</open:clientRequest>
</soapenv:Body>
</soapenv:Envelope>
So i have tried with xquery but its unable to do someone please responed for this
i have tried with this xquery
<x xmlns="http://ws.apache.org/ns/synapse">
declare namespace soapenv = "http://schemas.xmlsoap.org/soap/envelope";
declare namespace soap="http://schemas.xmlsoap.org/soap/envelope/";
declare namespace open="http://www.ffff.org/";
declare variable $emp as xs:string+:="http://uri.open.gen/com";
declare namespace env="http://eai.jj.mmm/Envelope";
declare variable $Request xs:string+ external;
declare variable $EaiEnvelope as document-node() external;
element{'open:clientRequest'}{
element{'*:EaiEnvelope'}{$EaiEnvelope//*:EaiEnvelope/*[not(local-name()='Payload')],
element{'*:Payload'}{
element{QName($emp,concat('emp',':','safety'))}
$Request//env:Payload/*[1]/*
}}
}
</x>
but its giving exception token is not specified
Thanks in advance

Answer 1

If XSLT 2.0 is an option for you (for example using saxon XSLT processor). You can apply this stylesheet to youe input:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:ss="http://eai.admc.kyt/security"
xmlns:emp="http://uri.open.gen/com"
version="2.0">
<xsl:template match="node()|#*">
<xsl:copy>
<xsl:apply-templates select="node()|#*"/>
</xsl:copy>
</xsl:template>
<xsl:template match="ss:*">
<xsl:element name="emp:{local-name()}">
<xsl:apply-templates select="node()|#*"/>
</xsl:element>
</xsl:template>
<xsl:template match="#ss:*">
<xsl:attribute name="emp:{local-name()}">
<xsl:apply-templates select="node()|#*"/>
</xsl:attribute>
</xsl:template>
</xsl:stylesheet>
Every attribute and element in http://eai.admc.kyt/security namespace in input will be in the other namespace in the output.
One note: it won't change in the comments

Here's an XQuery option...

The 2 XQuery functions can be combined to make it smaller, but I thought it was a little more readable.
