I want this to display the currentpage's children, if it doesn't have any children then it needs to display the sibilings of the currentpage.  Unless those sibilings are at root level.  Here is my code, please let me know what I need to do.  Thanks

<xsl:if test="count($currentPage/child::node [string(data [@alias='umbracoNaviHide']) != '1']) &gt; '0'">
<ul>
    <xsl:for-each select="$currentPage/node [string(data [@alias='umbracoNaviHide']) != '1'][string(./data [@alias='linkHide']) !='1']">
    <li>
        <xsl:choose>
            <xsl:when test="data [@alias='linkText'] != ''">
                <a href="{umbraco.library:NiceUrl(@id)}">
                <xsl:value-of select="data [@alias='linkText']" />
                </a>
            </xsl:when>
        <xsl:otherwise>
            <a href="{umbraco.library:NiceUrl(@id)}">
                <xsl:value-of select="@nodeName"/>
            </a>
        </xsl:otherwise>
        </xsl:choose>
    </li>
    </xsl:for-each>

</ul>
</xsl:if>
<xsl:if test="count($currentPage/child::node [string(data [@alias='umbracoNaviHide']) != '1']) = '0'">
<ul>
    <xsl:for-each select="$currentPage/parent::node/node [string(./data [@alias='umbracoNaviHide']) != '1'][string(./data [@alias='linkHide']) !='1']">
    <li>
        <xsl:choose>
            <xsl:when test="data [@alias='linkText'] != ''">
                <a href="{umbraco.library:NiceUrl(@id)}">
                <xsl:value-of select="data [@alias='linkText']" />
                </a>
            </xsl:when>
