Remove Duplicate Nodes From XML Payload Using XSLT

At the time of development sometimes it is required to remove the duplicate nodes from a XML payload depending upon some condition values. The following is a short example for the same.

• Created a BPEL process which input has multiple employee information. The xsd of the input payload looks like below.

• The input variable xml payload is looks like as given below.

• The below is XSLT code snippet which can be used to remove duplicate nodes which have the same employee id in the Input variable xml payload.

   <xsl:template match="@*|node()">

        <xsl:copy>

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

        </xsl:copy>

    </xsl:template>

    

   <xsl:template match="client:employee">

        <xsl:if test="not(following::client:employee[client:empid=current()/client:empid])">

            <xsl:copy>

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

            </xsl:copy>

        </xsl:if>   

    </xsl:template> 

• Below screenshot is the after transformation of the input variable.
