Can you nest xsl:if within nested xsl:when, for example: <xsl:choose> <xsl:when test=param/@id = ‘1’

Can you nest xsl:if within nested xsl:when, for example:

    <xsl:choose>
        <xsl:when test="param/@id  =  '1' " >
            <xsl:if test="param/value = 'XML' ">
                <xsl:when test="param/@id = '2' ">
                    <xsl:if test="param/value = 'HTTP' ">
                        <xsl:when test="param/@id = '3' ">
                            <xsl:if test="param/value = 'Y' ">
                                <xsl:call-template name="buildPayload"/>
                            </xsl:if>
                        </xsl:when>
                    </xsl:if>
                </xsl:when>
            </xsl:if>
        </xsl:when>
    </xsl:choose>

Can this be used, or is there away to streamline this into a more compact code?

    Without trying it: I’d think that <xsl:when> cannot be a child node of <xsl:if> without another <xsl:choose> in between. But, what are you trying to do? If I see that right, you want to run <call-template> if and only if (param/@id='1' and param/value='XML') or (param/@id='2' and param/value='HTTP') or (param/@id='3' and param/value='Y') … try that as the test value:

    <xsl:if test="(param/@id='1' and param/value='XML') or (param/@id='2' and param/value='HTTP') or (param/@id='3' and param/value='Y')">
    <xsl:call-template name="buildPayload"/>
</xsl:if>
