Unless a diligent XSLT implementor provides such a facility in an XSLT processor you may implement this stack yourself: <xsl:template match="A"> <xsl:param name="stack" /> ... <xsl:apply-templates> <xsl:with-param name="stack" select="concat('A - ', $stack)" /> </xsl:apply-templates> ... <xsl:message terminate="yes"> Template stack: <xsl:value-of select="$stack" /> </xsl:message> </xsl:template> <xsl:template match="B"> <xsl:param name="stack" /> ... <!-- dito --> </xsl:template> However, this seems to be quite laborious ...
