XSLT - Add new element and value-CodePudding

I have this XML and I want to add a new element name with a hard-coded value. How can I achieve it?

XML:

<m2:InvokeWebService xmlns:m2="http://www.w3.org/2001/XMLSchema-instance">
   <m2:request>
      <m2:action>ADD</m2:action>      
      <m2:commonDetails>
         <m2:needSupport>Y</m2:needSupport>
      </m2:commonDetails>
      <m2:custDetails>
         <m2:name>Tony,Hawk</m2:name>
         <m2:accountNumber>23232423566</m2:accountNumber>
         <m2:sensitiveCustomer>Y</m2:sensitiveCustomer>         
      </m2:custDetails>      
   </m2:request>
</m2:InvokeWebService>

Desired Output

<?xml version="1.0" encoding="UTF-8"?><m2:InvokeWebService xmlns:m2="http://www.w3.org/2001/XMLSchema-instance">
   <m2:request>
      <m2:action>ADD</m2:action>      
      <m2:commonDetails>
         <m2:needSupport>Y</m2:needSupport>
      </m2:commonDetails>
      <m2:overrideScriptName>NewScript</m2:overrideScriptName>
      <m2:custDetails>
         <m2:name>Tony,Hawk</m2:name>
         <m2:accountNumber>23232423566</m2:accountNumber>
         <m2:sensitiveCustomer>Y</m2:sensitiveCustomer>         
      </m2:custDetails>      
   </m2:request>
</m2:InvokeWebService>

XSLT:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"  xmlns:m2="http://www.w3.org/2001/XMLSchema-instance">
    <!--<xsl:output method="xml" encoding="utf-8" indent="yes"/>-->
    <!-- Identity template : copy all text nodes, elements and attributes -->   
    <xsl:template match="@*|node()">
        <xsl:copy>
            <xsl:apply-templates select="@*|node()" />
        </xsl:copy>
    </xsl:template>  
    <m2:overrideScriptName>CM-PrMtActMg</m2:overrideScriptName>      
</xsl:stylesheet>

New Element to be added right before the custDetails

<m2:overrideScriptName>NewScript</m2:overrideScriptName>

CodePudding user response：

Please try the following solution.

It is using a so called identity transform pattern.

Input XML

<m2:InvokeWebService xmlns:m2="http://www.w3.org/2001/XMLSchema-instance">
    <m2:request>
        <m2:action>ADD</m2:action>
        <m2:commonDetails>
            <m2:needSupport>Y</m2:needSupport>
        </m2:commonDetails>
        <m2:custDetails>
            <m2:name>Tony,Hawk</m2:name>
            <m2:accountNumber>23232423566</m2:accountNumber>
            <m2:sensitiveCustomer>Y</m2:sensitiveCustomer>
        </m2:custDetails>
    </m2:request>
</m2:InvokeWebService>

XSLT 1.0

<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:m2="http://www.w3.org/2001/XMLSchema-instance">
    <xsl:output method="xml" encoding="utf-8" indent="yes" omit-xml-declaration="no"/>
    <xsl:strip-space elements="*"/>

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

    <xsl:template match="m2:custDetails">
        <m2:overrideScriptName>NewScript</m2:overrideScriptName>
        <xsl:copy-of select="."/>
    </xsl:template>
</xsl:stylesheet>

Output XML

<?xml version='1.0' encoding='utf-8' ?>
<m2:InvokeWebService xmlns:m2="http://www.w3.org/2001/XMLSchema-instance">
  <m2:request>
    <m2:action>ADD</m2:action>
