    Choose or otherwise

    I have the following statement where i use a GetXmlNodeById to display to display the child nodes if there is any and if not to display a message.

    Am not sure what am doing wrong or missing something.

    <xsl:for-each select="umbraco.library:GetXmlNodeById($source)/*[@isDoc and string(umbracoNaviHide) != '1']">
              <xsl:choose>
                  <xsl:when test="count(./*[@isDoc and string(umbracoNaviHide) != '1']) &gt;0">
                    <xsl:value-of select="    somevalue"/>                           
                 </xsl:when>
                  <xsl:otherwise>
                        Do something else 
                   </xsl:otherwise>
            </xsl:choose>                
    </xsl:for-each>

    Hi Fuji

    What is the problem?

    Is it that the "Do something else" message is getting displayed or that it is never displayed?

    Hey Fuji,

    I think you want to move the <xsl:choose> outside of the for-each, otherwise the code inside the for-each will never be run if there are no child nodes from $source, right?  Or are you actually looking for child nodes of childs of source?

    How about...

    <xsl:variable name="sourceXml" select="umbraco.library:GetXmlNodeById($source)" />

    <xsl:choose>
      <xsl:when test="count($sourceXml/*[@isDoc and string(umbracoNaviHide) != '1']) &gt; 0">
        <xsl:for-each select="$sourceXml/*[@isDoc and string(umbracoNaviHide) != '1']">
          <xsl:value-of select="somevalue"/>                           
        </xsl:for-each>
      </xsl:when>
      <xsl:otherwise>
        Do something else (there are no children)
      </xsl:otherwise>
    </xsl:choose>              

    -Tom

    Hi Fuji,

    Set a variable to hold all the childnodes - do your for-each on that (or apply some templates).

    If the variable is empty, nothing will happen.

    Afterwards, do a simple if and print a message when the set was empty.

    <xsl:variable name="$sourceChildren" select="umbraco.library:GetXmlNodeById($source)/*[@isDoc][not(umbracoNaviHide = 1)]" />

<xsl:for-each select="$sourceChildren">
    <!-- Do stuff with the nodes -->
</xsl:for-each>
<xsl:if test="not($sourceChildren)">
    <!-- There's no spider here... -->
</xsl:if>

    Also: No need to count, and no need to string() anything - like a Mac, "it just works" :-)
