Copy XML as-is using XSLT and change One Attribute Value

[hangon]

Hi,

I have an xml input (wsse) and I want to change the value of one of the attribute "mustUnderstand" while copying.

Input.xml

<?xml version="1.0" encoding="UTF-8"?>
<env:Envelope
    xmlns:env = "http://schemas.xmlsoap.org/soap/envelope/"
    xmlns:xsd = "http://www.w3.org/2001/XMLSchema"
    xmlns:xsi = "http://www.w3.org/2001/XMLSchema-instance">
    <env:Header>
        <wsse:Security env:mustUnderstand = "1" xmlns:wsse = "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd">
            <wsse:UsernameToken xmlns:wsse = "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd">
                <wsse:Username xmlns:wsse = "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd">user</wsse:Username>
                <wsse:Password xmlns:wsse = "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd">password</wsse:Password>
            </wsse:UsernameToken>
        </wsse:Security>
    </env:Header>
    <env:Body>
        <ns0:addDispute xmlns:ns0 = "http://www.openuri.org/">
            <xmlString xsi:type = "def:string" xmlns:def = "http://www.w3.org/2001/XMLSchema"></xmlString>
        </ns0:addDispute>
    </env:Body>
</env:Envelope>

Stylesheet

<?xml version="1.0" encoding="windows-1252" ?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:env="http://schemas.xmlsoap.org/soap/envelope/" xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd">
<!-- Root template -->
<!-- "env:Envelope/env:Header/wsse:Security/@env:mustUnderstand" -->
   <xsl:template match="/">
      <xsl:copy>
         <xsl:apply-templates />
      </xsl:copy>
   </xsl:template>

   <xsl:template match="env:Envelope">
      <xsl:copy>
         <xsl:apply-templates />
      </xsl:copy>
   </xsl:template>

   <xsl:template match="env:Header">
      <xsl:copy>
         <xsl:apply-templates />
      </xsl:copy>
   </xsl:template>

   <xsl:template match="env:Body">
      <xsl:copy-of select="." />
   </xsl:template>

   <xsl:template match="wsse:Security">
      <xsl:copy>
         <xsl:attribute name="env:mustUnderstand">0</xsl:attribute>
      </xsl:copy>
      <xsl:apply-templates />
   </xsl:template>

   <xsl:template match="wsse:UsernameToken">
      <xsl:copy>
         <xsl:copy-of select="@*|node()" />
      </xsl:copy>
   </xsl:template>

</xsl:stylesheet>

I'm getting output

<?xml version="1.0" encoding="UTF-16"?>
<env:Envelope
    xmlns:env = "http://schemas.xmlsoap.org/soap/envelope/"
    xmlns:xsd = "http://www.w3.org/2001/XMLSchema"
    xmlns:xsi = "http://www.w3.org/2001/XMLSchema-instance">
    <env:Header>
        <wsse:Security env:mustUnderstand = "0" xmlns:wsse = "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd"/>
        <wsse:UsernameToken xmlns:wsse = "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd">
            <wsse:Username>wlisap</wsse:Username>
            <wsse:Password>saptest1</wsse:Password>
        </wsse:UsernameToken>
    </env:Header>
    <env:Body>
        <ns0:addDispute xmlns:ns0 = "http://www.openuri.org/">
            <xmlString xsi:type = "def:string" xmlns:def = "http://www.w3.org/2001/XMLSchema"></xmlString>
        </ns0:addDispute>
    </env:Body>
</env:Envelope>

As you can see in the section "wsse:Username" and "wsse:Password" I do not get the xmlns attributes.

Basically I want the complete Input as is and just change "env:mustUnderstand" from "1" to "0".

Thanks for the help in advance
