RE: [xsl] Dynamic Menu Using XSL

Remember that XSLT is used to generate the target HTML page, and if you want
any interaction on that page, e.g. hiding things when other things are
selected, that's purely a question of generating the HTML that exhibits that
behaviour.

So it's a two-stage process:

(a) design the (dynamic) HTML that you want to display 

(b) design the XSLT that generates it from your source XML.

I get the impression you haven't separated the two stages. It's a good idea
not to start on (b) until you have completed (a).

Subject: [xsl] Dynamic Menu Using XSL

I am trying to create a dynamic menu using XML and XSLT.  
Here is my XML

<?xml version="1.0" encoding="iso-8859-1" ?> <?xml-stylesheet 
type="text/xsl" href="mymenu.xsl"?>


<menu>
      <item id = "1" url="default.aspx" title="Home"></item>  
        <item id = "2" url="default.aspx?id=Training" 
title="Training">
              <item id = "3" 
url="default.aspx?id=Search_Training" title="Search Training"></item>
                <item id = "4" 
url="default.aspx?id=Post_Training" title="Post 
Training"></item>                     
        </item>  
        <item id = "7" url="default.aspx?id=Other_Training" 
title="Other Training">
              <item id = "8" 
url="default.aspx?id=Search_Other_Training" title="Search 
Other Training"></item>
                <item id = "9" 
url="default.aspx?id=Post_Other_Training" title="Post Other 
Training"></item>
        </item>
        <item id = "11" url="default.aspx?id=About_Us" 
title="About Us">
              <item id = "12" url="default.aspx?id=Location" 
title="Location">
                      <item id = "13" 
url="default.aspx?id=Map" title="View Map"></item>
              </item>
        </item>            
</menu>I am using the following XSLT to generate my HTML

<?xml version="1.0" encoding="utf-8"?>



<xsl:param name="URL"/>

  <xsl:output indent="yes"/>
  <xsl:template match="menu">
    <html>
      <body>
        <ul>
          <xsl:apply-templates/>
        </ul>
      </body>
    </html>
  </xsl:template>
  <xsl:template match="item">
    <li>
      <a href="{(_at_)url}">
        <xsl:value-of select="@title"/>
      </a>
      <xsl:if test="item">
        <ul>
          <xsl:apply-templates/>
        </ul>
      </xsl:if>
    </li>
  </xsl:template>

</xsl:stylesheet>

I would like to hide the child menu if the parent menu is not 
selected.   I would also like the parent menu to be expanded 
if a child menu is selected.  I am passing the url as a 
parameter (ex: default.aspx, default.aspx?id=About_us) this 
matches the URL attribute of the item.   I am new to XSLLT 
and would appreciate any help.

Thanks
Brant
