I am using XSLT to transform the xml response in my project.I have the following xml.
<?xml version="1.0" encoding="UTF-8"?>
<SOAP:Envelope xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/" SOAP:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
<SOAP:Body>
<response:performJobResponse xmlns:response="http://tempuri.org/" SOAP:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
<whiteboard>
<PQ>
<SOAP:Envelope SOAP:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
<SOAP:Body>
<response:performJobResponse SOAP:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
<whiteboard>
<PQ>
<SOAP:Envelope SOAP:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
<SOAP:Body>

I want to remove all the xmlns content,SOAP:Envelope, <SOAP:Body> and <response>tag related content.
My final xml should be as below:
<?xml version="1.0" encoding="UTF-8"?>
<PQ>
<PQContact>
<userID>Test</userID>
<password>Test#2</password>
</PQContact>
<workflowStatusComment>
<comment>Issue released. Routing Status changed from CATCHALL to Pharmancy. Issue updated by user DT76747.</comment>
</workflowStatusComment>
</PQ>
Could you please help me out?

Answer 1

Please, try this transformation:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:response="http://tempuri.org/">
<xsl:output method="xml" encoding="UTF-8" indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:template match="/">
<xsl:apply-templates select="//SOAP:Body/performJob//whiteboard/node()"/>
</xsl:template>
<xsl:template match="*">
<xsl:element name="{local-name(.)}">
<xsl:apply-templates/>
</xsl:element>
</xsl:template>
<xsl:template match="#*">
<xsl:copy/>
</xsl:template>
</xsl:stylesheet>
