[xsl] When I have a parent / has a subcat

How do I form the xsl so that I can put a "selected" class for the
parent of the child class I have currently selected?

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";

    <xsl:template match="menu">
        <xsl:choose>
            <xsl:when test="$leftNavId = 'nothing'">
                <!--do nothing-->
            </xsl:when>
        </xsl:choose>
        <ul class="adxm menu">
        <xsl:apply-templates select="category"/>
        </ul>
    </xsl:template>

    <xsl:template match="category">
