Adding namespace to child elements using xslt - xslt

Question

below is the input xml:
<ns:TXLife xmlns:ns="http://ACORD.org/Standards/Life/2">
<TXLifeResponse>
<TransRefGUID/>
<TransExeDate/>
<TransExeTime/>
<TransType tc="228"/>
</ns:TXLife>
and below is my XSLT :
xmlns:ns="http://ACORD.org/Standards/Life/2" version="1.0">
<xsl:output omit-xml-declaration="yes" indent="yes"/>
<xsl:template match="/">
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:acor="http://www.foresters.com/esb/ws/wsdl/ACORD-v1.0" xmlns:ns="http://ACORD.org/Standards/Life/2">
<soapenv:Header/>
<soapenv:Body>
<xsl:copy>
<xsl:apply-templates />
</xsl:copy>
</soapenv:Body>
</soapenv:Envelope>
</xsl:template>
<xsl:template match="node() [local-name(.) = 'TXLife']">
<xsl:element name="ns:{local-name()}">
<xsl:apply-templates select="#*|node()"/>
</xsl:element>
</xsl:template>
By using this tranformation i am not able to add namespace prefix to all the child element of TXLife.
how to add namespace prefix (ns) to all child elements? so that it should look as below
<ns:TXLifeResponse>
<ns:TransRefGUID/>
<ns:TransExeDate/>
<ns:TransExeTime/>
<ns:TransType tc="228"/>
</ns:TXLife>

Answer 1

If you want only TXLife and descendant to be under http://ACORD.org/Standards/Life/2 namespace, use this stylesheet:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:ns="http://ACORD.org/Standards/Life/2"
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<xsl:template match="/">
<soapenv:Envelope>
<soapenv:Header/>
<soapenv:Body>
<xsl:apply-templates/>
</soapenv:Body>
</soapenv:Envelope>
</xsl:template>
<xsl:template match="*[ancestor-or-self::ns:TXLife]">
<xsl:element name="ns:{local-name()}">
<xsl:apply-templates select="#*|node()"/>
</xsl:element>
</xsl:template>
<xsl:template match="#*|node()">
<xsl:copy>
<xsl:apply-templates select="#*|node()"/>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
Output:
<soapenv:Envelope
xmlns:ns="http://ACORD.org/Standards/Life/2"
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<soapenv:Header />
<soapenv:Body>
<ns:TXLife>
<ns:TXLifeResponse>
<ns:TransRefGUID></ns:TransRefGUID>
<ns:TransExeDate></ns:TransExeDate>
<ns:TransExeTime></ns:TransExeTime>
<ns:TransType tc="228"></ns:TransType>
</ns:TXLifeResponse>
</ns:TXLife>
</soapenv:Body>
</soapenv:Envelope>

Answer 2

Your XML isn't valid, but I assume you just've missed the closing TXLifeResponse element.
The following transformation will do what you want:
XML:
<?xml version="1.0" encoding="UTF-8"?>
<ns:TXLife xmlns:ns="http://ACORD.org/Standards/Life/2">
<TXLifeResponse>
<TransRefGUID/>
<TransExeDate/>
<TransExeTime/>
<TransType tc="228"/>
</TXLifeResponse>
</ns:TXLife>
XSLT:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"
xmlns:ns="http://ACORD.org/Standards/Life/2">
<xsl:output omit-xml-declaration="yes" indent="yes"/>
<xsl:template match="/">
<soapenv:Envelope
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:acor="http://www.foresters.com/esb/ws/wsdl/ACORD-v1.0"
xmlns:ns="http://ACORD.org/Standards/Life/2">
<soapenv:Header/>
<soapenv:Body>
<xsl:copy>
<xsl:apply-templates/>
</xsl:copy>
</soapenv:Body>
</soapenv:Envelope>
</xsl:template>
<xsl:template match="*">
<xsl:element name="ns:{local-name()}">
<xsl:apply-templates select="#*|node()"/>
</xsl:element>
</xsl:template>
<xsl:template match="#*">
<xsl:copy-of select="."/>
</xsl:template>
</xsl:stylesheet>
Output:
<soapenv:Envelope
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:acor="http://www.foresters.com/esb/ws/wsdl/ACORD-v1.0"
xmlns:ns="http://ACORD.org/Standards/Life/2">
<soapenv:Header/>
<soapenv:Body>
<ns:TXLife>
<ns:TXLifeResponse>
<ns:TransRefGUID/>
<ns:TransExeDate/>
<ns:TransExeTime/>
<ns:TransType tc="228"/>
</ns:TXLifeResponse>
</ns:TXLife>
</soapenv:Body>
</soapenv:Envelope>
The template xsl:template match="node()[local-name(.) = 'TXLife']" is somewhat strange to me. What are you trying to accomplish? Maybe we can help explain why this isn't the appropriate way to do it.
