Input-Output transformation remove nodes and update nodes - xslt

Question

How to translate the given input xml into the output as shown below.
The input xml should be transformed by removing the wsse:Security header completely and EventUser value must be updated with the Username node value.
I tried below xlst. It is not working
XLST -
<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="EventUser">
<xsl:copy>
<xsl:value-of select="Username"/>
</xsl:copy>
</xsl:template>
<xsl:template match="#*|node()">
<xsl:copy>
<xsl:apply-templates select="#*|node()"/>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
Input -
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<soapenv:Header>
<wsse:Security mustUnderstandValue="1"
xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd">
<wsse:UsernameToken id="UsernameToken-274">
<wsse:Username>MyUsername</wsse:Username>
<wsse:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText">Password</wsse:Password>
</wsse:UsernameToken>
</wsse:Security>
</soapenv:Header>
<soapenv:Body>
<axis2ns682:Create xmlns:axis2ns682="http://g22.test01.org/test02/RF">
<tns:CreateDetails xmlns:tns="http://g22.test01.org/test02/RF">
<tns:EventUser>Event</tns:EventUser>
<tns:PreApprovedTemplateID>221398</tns:PreApprovedTemplateID>
<tns:Priority>High</tns:Priority>
<tns:PlannedImplementation_Start>2017-09-29</tns:PlannedImplementation_Start>
</tns:CreateDetails>
</axis2ns682:Create>
</soapenv:Body>
</soapenv:Envelope>
Output -
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<soapenv:Header>
</soapenv:Header>
<soapenv:Body>
<axis2ns682:Create xmlns:axis2ns682="http://g22.test01.org/test02/RF">
<tns:CreateDetails xmlns:tns="http://g22.test01.org/test02/RF">
<tns:EventUser>MyUsername</tns:EventUser>
<tns:PreApprovedTemplateID>221398</tns:PreApprovedTemplateID>
<tns:Priority>High</tns:Priority>
<tns:PlannedImplementation_Start>2017-09-29</tns:PlannedImplementation_Start>
</tns:CreateDetails>
</axis2ns682:Create>
</soapenv:Body>
</soapenv:Envelope>

Answer 1

You have three problems with your XSLT
You have not accounted for namespaces in your XSLT. In your XML, the elements are in various namespaces (the EventUser element is in namespace http://g22.test01.org/test02/RF as denoted by the tns: prefix.
You have not coded anything to remove the wsse:Security element
The template matching EventUser is selecting Username, which would only would if Username was a child of EventUser. You actually need to select it from the soap:Header
Try this XSLT
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:tns="http://g22.test01.org/test02/RF"
xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd"
version="1.0">
<xsl:template match="wsse:Security" />
<xsl:template match="tns:EventUser">
<xsl:copy>
<xsl:value-of select="//soapenv:Header/wsse:Security/wsse:UsernameToken/wsse:Username"/>
</xsl:copy>
</xsl:template>
<xsl:template match="#*|node()">
<xsl:copy>
<xsl:apply-templates select="#*|node()"/>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
