remove xml element xsl

[Juan Luis Prieto]

I am trying to remove an element from an xml message and I have reached the point to remove the content of the element I want to remove, but not the entire element as I want. I have to do it by applying an stylesheet transformation by xsl.

This is my message and the element I want to remove is <user:username xmlns:user="http://www.bt.com/ssc-User">juanlu</user:username>

<?xml version="1.0" encoding="UTF-8"?>
<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope">
	<soap:Header>
		<wsa:To xmlns:wsa="http://www.w3.org/2005/08/addressing">http://localhost:7070/WsSongStore/services/WsSongStore</wsa:To>
		<wsa:Action xmlns:wsa="http://www.w3.org/2005/08/addressing">http://songstore.org/cap/mgmt/CreateOperation</wsa:Action>
		<wsa:MessageID xmlns:wsa="http://www.w3.org/2005/08/addressing">uuid:fe33274e-1ca7-daca-ceab-13e4417560c2</wsa:MessageID>
		<wsa:From xmlns:wsa="http://www.w3.org/2005/08/addressing">
			<wsa:Address>http://www.w3.org/2005/08/addressing/role/anonymous</wsa:Address>
		</wsa:From>
		<vSTS:FederationUUID xmlns:vSTS="http://www.bt.com/Vordel-STS">aaaaaaaa-aaaa-aaaa-aaaa-aaaaaaaaaaaa</vSTS:FederationUUID>
		<vSTS:businessKey xmlns:vSTS="http://www.bt.com/Vordel-STS">1a555434-ca9e-4c31-b59a-dc3c07f6dad1</vSTS:businessKey>
		<user:username xmlns:user="http://www.bt.com/ssc-User">juanlu</user:username>
	</soap:Header>
	<soap:Body>
		<pfx1:CreateOperation xmlns:pfx1="http://songstore.org/cap/mgmt"/>
	</soap:Body>
</soap:Envelope>

This is the xsl that I am applying to the message.

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:fn="http://www.w3.org/2005/xpath-functions" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:wsa="http://www.w3.org/2005/08/addressing">
	<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
	<xsl:template match="node()|@*">
		<xsl:copy>
		<xsl:choose>
			<xsl:when test="local-name()!='username'">
				<xsl:apply-templates select="node()|@*|*|processing-instruction()|comment()|text()"/>
			</xsl:when>
		</xsl:choose>
		</xsl:copy>
	</xsl:template>
</xsl:stylesheet>

And this is the exit I have.

  
<?xml version="1.0" encoding="UTF-8"?>
<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope">
	<soap:Header>

		<wsa:From xmlns:wsa="http://www.w3.org/2005/08/addressing">
			<wsa:Address>http://www.w3.org/2005/08/addressing/role/anonymous</wsa:Address>
		</wsa:From>
		<vSTS:FederationUUID xmlns:vSTS="http://www.bt.com/Vordel-STS">aaaaaaaa-aaaa-aaaa-aaaa-aaaaaaaaaaaa</vSTS:FederationUUID>
		<vSTS:businessKey xmlns:vSTS="http://www.bt.com/Vordel-STS">1a555434-ca9e-4c31-b59a-dc3c07f6dad1</vSTS:businessKey>
		<user:username xmlns:user="http://www.bt.com/ssc-User"/>
	</soap:Header>
	<soap:Body>
		<pfx1:CreateOperation xmlns:pfx1="http://songstore.org/cap/mgmt"/>
	</soap:Body>
</soap:Envelope>

Do you know what is wrong with the stylesheet not for it to remove the element I want?

Thanks.

I have fixed it, the problem was the copy that is not in the correct position.
This is how it should be.

	<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
	<xsl:variable name="tag">username</xsl:variable>
	<xsl:template match="node()|@*">

			<xsl:when test="local-name()!=$tag">
				<xsl:copy>

				</xsl:copy>
			</xsl:when>
		</xsl:choose>
	</xsl:template>
</xsl:stylesheet>
