Hi Pragya,

If you are using XSLT, please try below code and see if this helps,

 <xsl:template match="@*|node()">
        <xsl:choose>
            <xsl:when test="descendant-or-self::text()[normalize-space(.)
ne '']">
                <xsl:copy>
                    <xsl:apply-templates select="@* | node()"/>
                </xsl:copy>
            </xsl:when>
            <xsl:otherwise/>
        </xsl:choose>
    </xsl:template>

Thank you!
