Thank you Elliot for your help.
Sorry for troubling again.
outputFlagStyle is calling in the below two places, but i am not able to see any text node before the template call.
<xsl:template name="parseFlagStyle">
<xsl:param name="value"/>
<xsl:choose>
<xsl:when test="$value = ''"/>
<xsl:when test="contains($value,';')">
<xsl:variable name="firstValue" select="substring-before($value,';')"/>
<xsl:call-template name="outputFlagStyle">
<xsl:with-param name="value">
<xsl:value-of select="$firstValue"/>
</xsl:with-param>
</xsl:call-template>
<xsl:call-template name="parseFlagStyle">
<xsl:with-param name="value" select="substring-after($value,';')"/>
</xsl:call-template>
</xsl:when>
<xsl:otherwise>
<xsl:call-template name="outputFlagStyle">
<xsl:with-param name="value">
<xsl:value-of select="$value"/>
</xsl:with-param>
</xsl:call-template>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
<xsl:template match="suitesol:flagging-inside">
<xsl:call-template name="parseFlagStyle">
<xsl:with-param name="value">
<xsl:value-of select="@style"/>
</xsl:with-param>
<xsl:apply-templates />
</xsl:call-template>
</xsl:template>
Thanks in advance
