Error in adding multiple namespace to the output XML

Question

I am trying to generate an XML output from the given input XML using XSLT. The output xml will have different namespaces added to it at various level of the xml tree. I am using XPath axes (descendant) to add the namespace to children nodes, but it outputs the grandchildern nodes next to children node.

My Input XML

<?xml version="1.0" encoding="UTF-8"?>
<request>
   <header>
      <sender>
         <User>ServiceUser</User>
         <userid type="UserId">ServiceUserid</userid>
      </sender>
      <receiver>
         <Country>IND</Country>
      </receiver>     
      <id>123456</id>
   </header>
   <Address type="physical">
      <subaddress>
         <number>2</number>
      </subaddress>
      <doornumber>13</doornumber>
      <streetName>mgr road</streetName>
      <locality>cityname</locality>
      <postalcode>612453</postalcode>
   </Address>
</request>

My XSLT

    <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
    <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:aa="xyz.com/aa"

Can you someone please help me with the correct xslt to produce the expected result. Thank you in advance.

Your stylesheet is tagged as version="1.0" but you use xsl:namespace which is only available in XSLT 2.0. Are you in fact using an XSLT 2.0 processor? — michael.hor257k

@michael, it should be <number> without namespace. This xslt will be processed by a third party tool which supports both XSLT 1.0 and 2.0. — jack

Why can't you do simply:

XSLT 1.0

<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:bb="xyz.com/header"
xmlns:aa="xyz.com/request"
xmlns:addr="xyz.com/address">
<xsl:output method="xml" omit-xml-declaration="yes" version="1.0" encoding="utf-8" indent="yes"/>
<xsl:strip-space elements="*"/>

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

<xsl:template match="/request">
    <soapenv:Envelope >
        <soapenv:Header/>
        <soapenv:Body>
            <aa:request xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
                <xsl:apply-templates/>
            </aa:request>
        </soapenv:Body>
    </soapenv:Envelope>
</xsl:template>

<xsl:template match="*[ancestor-or-self::header]">
    <xsl:element name="bb:{local-name()}">
        <xsl:apply-templates select="node()|@*" />
    </xsl:element>
</xsl:template>

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

<xsl:template match="*[parent::Address]">
    <xsl:element name="addr:{local-name()}">
        <xsl:apply-templates select="node()|@*" />
    </xsl:element>
</xsl:template>

</xsl:stylesheet>

Note: the xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" declaration is not being used and therefore entirely redundant.

thanks for your reply. I am new to XSLT and still learning it. Will try your XSLT.
