从xml中删除空元素和属性，但使用xslt复制所有namepsce

Question

I have below xml and trying to remove the empty xml elements and attributes. but have to copy all the namespace into the xml. the XSLT which i am using is working fine. but the only problem i am facing here, it's also removing the xmlns:temp-root="http://xx.xxxxx.com" namespace from the xml. Not sure why it's been removed from the output xml. can somebody please help me to resolve this issue.

Hope this helps. This is for changing the namespaces.

XML

<?xml version='1.0' encoding='utf-8'?>
    <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
        <soapenv:Body>
            <temp-root:xxxxx_update xmlns:temp-root="http://xx.xxxxx.com" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
                <firstname>Kevin</firstname>
                <Status>false</Status>
                <lastname>John</lastname>
                <balance>
                    <tn:balance_InnerSet xmlns:tn="xxxxxxxxxxxxx">
                        <tn:balancesheet>
                            <tn:account>
                                <tn:accounttype>savings</tn:accounttype>
                                <tn:accountno>123456789</tn:accountno>
                            </tn:account>
                        </tn:balancesheet>
                    </tn:balance_InnerSet>
                </balance>
            </temp-root:xxxxx_update>
        </soapenv:Body>
    </soapenv:Envelope>

XSL

<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:output indent="yes"/>
    <xsl:strip-space elements="*"/>

    <xsl:template match="@*|node()">
        <xsl:copy>
            <xsl:apply-templates select="@*|node()"/>
        </xsl:copy>
    </xsl:template>

    <xsl:template match="temp-root">
        <xsl:element name="temp-root:{local-name()}" namespace="http://xx.xxxxx.com">
            <xsl:namespace name="xsi" select="'http://www.w3.org/2001/XMLSchema-instance'"/>
            <xsl:apply-templates select="@*|node()"/>
        </xsl:element>
    </xsl:template>

</xsl:stylesheet>
