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>
