Hi,

I'm currently stuck trying to modify my websites navigation header menu using xslt through Umbraco (I'm a bit of a novice when it comes to xslt unfortunately). The menu has 2 levels and functions correctly but I would like to remove the extension of the URLs so that it displays SEO friendly URLs e.g. change http://www.home.com/about-us.aspx to http://www.home.com/about-us

The current code is below:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE xsl:stylesheet [ <!ENTITY nbsp "&#x00A0;"> ]>
<xsl:stylesheet 
  version="1.0" 
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
  xmlns:msxml="urn:schemas-microsoft-com:xslt" 
  xmlns:umbraco.library="urn:umbraco.library" xmlns:Exslt.ExsltCommon="urn:Exslt.ExsltCommon" xmlns:Exslt.ExsltDatesAndTimes="urn:Exslt.ExsltDatesAndTimes" xmlns:Exslt.ExsltMath="urn:Exslt.ExsltMath" xmlns:Exslt.ExsltRegularExpressions="urn:Exslt.ExsltRegularExpressions" xmlns:Exslt.ExsltStrings="urn:Exslt.ExsltStrings" xmlns:Exslt.ExsltSets="urn:Exslt.ExsltSets" 
  exclude-result-prefixes="msxml
 umbraco.library Exslt.ExsltCommon Exslt.ExsltDatesAndTimes 
Exslt.ExsltMath Exslt.ExsltRegularExpressions Exslt.ExsltStrings 
Exslt.ExsltSets ">

<xsl:output method="xml" omit-xml-declaration="yes" />

<xsl:param name="currentPage"/>

<xsl:variable name="level" select="1"/>

<xsl:template match="/">

<!-- The fun starts here -->
<ul id="main-nav" class="sf-js-enabled sf-shadow">
<xsl:for-each select="$currentPage/ancestor-or-self::* [@level=$level]/* [@isDoc and string(umbracoNaviHide)!= '1']">
  <li class="main_menu_padiing">
    <a href="{umbraco.library:NiceUrl(@id)}" class="sf-with-ul">
    <xsl:value-of select="@nodeName"/>
    </a>

     <xsl:if test="count(current()/* [@isDoc]) > 0">
 <ul>
        <xsl:for-each select="current()/* [@isDoc and string(umbracoNaviHide) != '1']">
          <li>
              <a href="{umbraco.library:NiceUrl(@id)}" class="sf-with-ul">
                <xsl:value-of select="@nodeName" />
            </a>
          </li>
        </xsl:for-each>
      </ul>
</xsl:if>

  </li>
</xsl:for-each>
</ul>

</xsl:template>

</xsl:stylesheet>

I have managed to remove the extensions using the following code (however this has led to a bug within the menu):

 <xsl:if test="count(current()/* [@isDoc]) > 0">
 <ul>
        <xsl:for-each select="current()/* [@isDoc and string(umbracoNaviHide) != '1']">
          <li>
              <a href="{umbraco.library:Replace(umbraco.library:NiceUrl(@id),'.aspx','')}" class="sf-with-ul">
                <xsl:value-of select="@nodeName" />
            </a>
          </li>
        </xsl:for-each>
      </ul>
</xsl:if>

Basically I think the above code somehow confuses the @isDoc and string(umbracoNaviHide) != '1' check as on the second level of the menu unwanted pages appear (basically any page within the Home folder in the Content tab of Umbraco). For example the correct menu structure would be:

Home: About, Contact

However with the code implemented that replaces '.aspx' the following menu structure is displayed:

Home: About, Contact, Page Not Found, pdfviewer

If anyone know of a solution on how to remove the URL extension and retain the correct menu structure then any help would be very much appreciated!

Thanks,

Daniel
