    Hi,

    To check the child node you have to check counting of the child nodes. Here is sample code

    <xsl:for-each select="$currentPage/* [@isDoc and string(umbracoNaviHide) != '1']">
    <xsl:variable name="child" select="umbraco.library:GetXmlNodeById(@id)/*[@isDoc]"/>
            <xsl:if test="count($child) > 0">
    <xsl:value-of select="@nodeName"/>
            </xsl:if>
    </xsl:for-each>

    Hope this helps

    @ Pasang ..... i want to check whether current node has child node & if yes then it will go into for-each loop ....

    @Daniel .....I used that if statement but it is showing text even if there is no child node .....

    Hi guys,

    I actually just tryed to achieve the same here (check if current node I am iterating on has any children) and Vaibhavs suggestion just worked for me.

     

    <xsl:if test="current()/* [@isDoc and string(umbracoNaviHide) != '1']">    <!-- checking for child nodes  -->
                  <ul id="list-content">
                    <xsl:for-each select="current()/child::* [@isDoc and string(umbracoNaviHide) != '1']">
                      <li>
                        <a href="{umbraco.library:NiceUrl(@id)}" class="M2">
                          <xsl:value-of select="@nodeName"/>
                        </a>                      
                      </li>
                    </xsl:for-each> 
                  </ul>
        </xsl:if>

    I have  a similar need, but I need to check only the top level parents in a <ul> to see if they have children and if they don't apply a <href>. All subsuquent children should allways have a link applied to them though. Any ideas?

    Page I am woring with:

    Here's an example of using this in a hierarchical list:

    <ul class="navClearLevel1Ul">
    <xsl:for-each select="$currentPage/ancestor-or-self::* [@level=$level]/* [@isDoc and string(umbracoNaviHide) != '1']">
    <li class="navClearLevel1Li">
        <a href="{umbraco.library:NiceUrl(@id)}">
            <xsl:value-of select="@nodeName"/>
        </a>
        <xsl:variable name="child" select="umbraco.library:GetXmlNodeById(@id)/*[@isDoc]"/>
        <xsl:if test="count($child) &gt; 0">
        <ul class="navClearLevel2Ul">
            <xsl:for-each select="@nodeName/ancestor-or-self::* [@level=$level2]/* [@isDoc and string(umbracoNaviHide) != '1']">
            <li class="navClearLevel2Li">
                <a href="{umbraco.library:NiceUrl(@id)}">
                    <xsl:value-of select="@nodeName"/>
                </a>
            </li>
            </xsl:for-each>
        </ul>
        </xsl:if>
    </li>
    </xsl:for-each>
    </ul>
