I have a proxy which needs to do XSL transformation of an output message coming from the service. I have attached the sequence file and the XSL file (at synaptic-configs/local-entries).
Appreciate if you can give a hint on where I might have gone wrong.
Here’s the sequence file:
<?xml version="1.0" encoding="UTF-8"?>
<sequence xmlns="http://ws.apache.org/ns/synapse" name="EmpMergeOutSeq1" trace="enable" statistics="enable">
<log level="full">
<property name="sequence" value="Final Transform using XSLT - begin"/>
</log>
<xslt key="getEmployeeByIdResponseXlt"/>
<send/>
</sequence>
Here’s the XSL file:
<?xml version="1.0" encoding="UTF-8"?>
<localEntry xmlns="http://ws.apache.org/ns/synapse" key="getEmployeeByIdResponseXlt">
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:ax21="http://domain.hrapp.gunith/xsd" xmlns:ns="http://service.hrapp.gunith" xmlns:fn="http://www.w3.org/2005/02/xpath-functions" version="2.0" exclude-result-prefixes="ns fn">
<xsl:output method="xml" omit-xml-declaration="yes" indent="yes"/>
<xsl:template match="/">
<xsl:apply-templates select="//ns:getEmployeeByIdResponse"/>
</xsl:template>
<xsl:template xmlns:ns="http://samples.esb.wso2.org" match="ns:getEmployeeByIdResponse">
<ns1:getEmployeeByIdResponse xmlns:ns1="http://service.proxy.gunith">
<ns1:return xmlns:ax22="http://domain.proxy.gunith/xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="ax22:Employee">
<ax22:dob>
<xsl:value-of select="ns:return/ax21:dob"/>
</ax22:dob>
<ax22:firstName>
<xsl:value-of select="ns:return/ax21:firstName"/>
</ax22:firstName>
<ax22:id>
<xsl:value-of select="ns:return/ax21:id"/>
</ax22:id>
<ax22:lastName>
<xsl:value-of select="ns:return/ax21:lastName"/>
</ax22:lastName>
<ax22:middleName>
<xsl:value-of select="ns:return/ax21:middleName"/>
</ax22:middleName>
</ns1:return>
</ns1:getEmployeeByIdResponse>
</xsl:template>
</xsl:stylesheet>
</localEntry>
Here are the log entries (which shows the Errors and the actual messages passed):

THANK YOU!
Issue is at your xslt script..What you can do is try in eclipse/any other xslt processor feed the soap message as input xml for this xslt script and run..If the script is right, you will get output else not…
