Hello everybody!

 

I am working with at xslt leftmenu!

 

This is what I have inserted in my page template:

 

<!--@If Defined(LeftMenu)--> 
    <div id="leftmenu">
        <div id="navigation">
        <div class="nav_header">

            <span><!--@DwTopPageName--></span>

        </div>
        <!--@LeftMenu-->
        <div class="nav_spacer"></div>
       </div>
    </div>

<!--@EndIf(LeftMenu)-->

 

It workes fine on pages with submenus, but when I have a page with no submenus, it doens't hide, and this is the output i get:

 

<div id="leftmenu">
    <div id="navigation">
        <div class="nav_header"><span>Menu</span></div>             <ul />
        <div class="nav_spacer"></div>
    </div> </div>



I don't know why and where the <ul /> comes from?!

Can anybody help me with this problem??

Thanks

That  <ul /> comes from your xslt. And since if defined looks for an empty string, and navigation xslt returns something - it will be displayed.

 

So find the error in your xslt and make sure it returns nothing at all if it get no nodes.

I also thought that, but I have now testet the xslt file on our own solution with success.

 

I know that the new solution not has been updated to the newest version. Can that have something to do with it?

Just checked the xml/xslt parsing. Changes has not been done there.

 

XML output could have changed a little. Could you provide the xml documents for both solutions with not sub items? (Use SaveXML=true to save xml document to /Files/Templates/Navigation)

I have isolated the object which is outputtet even when there is no subitems. It is the first <ul> marked with green.

 

Does it make any sense for you?

 <xsl:output method="xml" omit-xml-declaration="yes" indent="yes"  encoding="utf-8" />
  <xsl:param name="html-content-type" />
  <xsl:template match="/NavigationTree"> 
    
    <ul>
      <xsl:apply-templates select="Page">
        <xsl:with-param name="depth" select="1"/>
      </xsl:apply-templates>
    </ul>

  </xsl:template>

One of the attached xml files contains navigation items - thats a difference.

But in your xslt add an if on the count of pages nodes meeting your criterias. If there are no nodes, return nothing.

Hi Guys

Sorry for hi-jacking this thread ...

 

In you XSLT your first template matches /NavigationTree and if that exists it generates the UL tag no matter if the XML contains any Page nodes or not.

 

So what you need to do is to match /NavigationTree[Page] instead.

 

This will look for a NavigationTree node with Page children. And then it will only generate the UL when the XML contains Page nodes.

Amazing!! That did it! Thank you very much Sebastian! Also thank you Nicolai for you effort!

 

Maybe I should begin reading the xml/xslt book I have ordered long time ago :)

 

Have a nice weekend both of you... you just saved mine!

OK Dammark - I get a hint. I'll stay away from this category...
