Question

I am trying to add a piece of an XML to an input XML using XSLT. But the output is not coming as expected. Pelase help.

My input XML :

    <input  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  xsi:noNamespaceSchemaLocation="nbA2.8.90.xsd">
        <nodeA id="test">
            <inodeAA> Sample </inodeAA>
            <inodeAB> Samples </inodeAB>
        </nodeA>
        <nodeB id="test">
            <inodeBA> Sample </inodeBA>
            <inodeBB> Samples </inodeBB>
        </nodeB>
    </input>

Below is another XML piece which I am passing as a parameter to me XSLT.
This piece is to be added to the input XML:

    <ns3:output xmlns:ns3="http://mysample.org">
        <ns3:reply id="rep">
            <ns3:zip>55555</ns3:zip>
            <ns3:place>SampleLoc</ns3:place>
        </ns3:reply>
    </ns3:output>

Below is my Expected Output:

    <input xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  xsi:noNamespaceSchemaLocation="nbA2.8.90.xsd">
        <nodeA id="test">
            <inodeAA> Sample </inodeAA>
            <inodeAB> Samples </inodeAB>
        </nodeA>
        <nodeB id="test">
            <inodeBA> Sample </inodeBA>
            <inodeBB> Samples </inodeBB>
        </nodeB>

        <ns3:output xmlns:ns3="http://mysample.org">
            <ns3:reply id="rep">
                <ns3:zip>55555</ns3:zip>
                <ns3:place>SampleLoc</ns3:place>
            </ns3:reply>
        </ns3:output>

    </input>

Below is the XSL I am using for this task:

In the below XSLT the param “outParam” holds the xml piece which I am trying to add to me input.

    <xsl:stylesheet version="2.0"
        xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
        xmlns:ns3="http://mysample.org"
        exclude-result-prefixes="soap xsl">
        <xsl:output omit-xml-declaration="yes" indent="yes" />

        <xsl:param name="outParam"></xsl:param>

        <xsl:template match="input">
            <input>
                <xsl:copy-of copy-namespaces="no" select="./@*" />
                <xsl:copy-of copy-namespaces="no" select="node() | @*" />
            </input>
            <xsl:copy >
                <xsl:value-of select="$outParam" disable-output-escaping="yes" ></xsl:value-of>
            </xsl:copy>
        </xsl:template> 
    </xsl:stylesheet>

Below is the output I am getting. This is not matching my expected output.

    <input xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xmlns:ns3="http://mysample.org"  
        xsi:noNamespaceSchemaLocation="nbA2.8.90.xsd" >
        <nodeA id="test">
            <inodeAA> Sample </inodeAA>
            <inodeAB> Samples </inodeAB>
        </nodeA>
        <nodeB id="test">
            <inodeBA> Sample </inodeBA>
            <inodeBB> Samples </inodeBB>
        </nodeB>
    </input>
    <input xmlns:xsd="http://www.w3.org/2001/XMLSchema"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">   
        <ns3:output xmlns:ns3="http://mysample.org">
            <ns3:reply id="rep">
                <ns3:zip>55555</ns3:zip>
                <ns3:place>SampleLoc</ns3:place>
            </ns3:reply>
        </ns3:output>
    </input>

Please help. I have tried many combinations but no luck. 🙁

Note: I am performing this transformation using the Mule XSLT Transformer which transforms payload XML based on the XSLT provided.

If the parameter is a node or sequence of nodes all you need is

<xsl:template match="input">
  <xsl:copy>
     <xsl:copy-of select="@* , node(), $outParam"/>
  </xsl:copy>
</xsl:template>

If the parameter passed in is a string with XML markup then you need

<xsl:template match="input">
  <xsl:copy>
    <xsl:copy-of select="@*, node()"/>
    <xsl:value-of select="$outParam" disable-output-escaping="yes"/>
  </xsl:copy>
</xsl:template>
