You could simply call xsl:apply-templates with the match attribute set to the element name. If the element exists the template is called. It it does not exist, the template won't be called. If you are trying to build a if-else statement you could check the existence like this

<xsl:choose>
    <xsl:when test="boolean(price)">
        <!-- do something -->
    </xsl:when>
    <xsl:otherwise>
        <!-- do something else -->
    </xsl:otherwise>
</xsl:choose>

So you can check for existence of an element and react accordingly.
