Remove empty nodes in BizTalk by using XSLT

You can get rid of the empty nodes in your map by using a custom functoid and use XSLT script (also given below) and mentioned in this article

<?xml version="1.0" ?>

<xsl:stylesheet xmlns:xsl="@@ YOUR NAMESPACE @@" version="1.0" xmlns:ns0="http://Stater.Isvcs.Iface.BO.GetLoanData.ElfV2">

    <xsl:output method="xml" indent="yes" />

    <xsl:template match="node()">

        <xsl:if test="count(descendant::text()[string-length(normalize-space(.))>0]|@*)">

            <xsl:copy>

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

            </xsl:copy>

        </xsl:if>

    </xsl:template>

    <xsl:template match="@*">

        <xsl:copy />

    </xsl:template>

    <xsl:template match="text()">

        <xsl:value-of select="normalize-space(.)" />

    </xsl:template>

</xsl:stylesheet>
