<?xml version='1.0' encoding='utf-8'?>
<soapenv:Envelope xmlns:soapenv="http://www.w3.org/2003/05/soapenvelope">
<soapenv:Body>
<Entries xmlns="http://ws.wso2.org/dataservice">
<Entry>
<empId>xxx</empId>
<empName>yyy</empName>
<allocatedDesk>null</allocatedDesk>
</Entry>
</Entries>
</soapenv:Body>
</soapenv:Envelope>

You can use a XSLT to replace the "null":
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xpath-default-namespace="http://ws.wso2.org/dataservice" version="2.0">
<xsl:output method="xml" encoding="utf-8" indent="yes"/>
<xsl:template match="/soapenv:*">
<xsl:copy>
<xsl:apply-templates/>
</xsl:copy>
</xsl:template>
<xsl:template match="allocatedDesk[text()='null']">
<xsl:copy>
<xsl:value-of select="'YOUR DESIRED TEXT'"/>
</xsl:copy>
</xsl:template>
<xsl:template match="*|node()|#*">
<!-- copy all elements -->
<xsl:copy>
<xsl:apply-templates/>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
The xslt mediator is being used to apply the XSLT on your MessageContext in WSO2. See the documentation:
