I'm using jquery treeview to create a help site for our product. I'm using XSLT to render out the navigation menu and letting jQuery.Treeview do the rest.

I need to render the whole treeview each time (for each page) and obviously highlight the current page. A node in the treeview can either be a link node to that page, or a group node that when selected simply expands down revealing the options.

For example:

+ Guide
   + Reporting
      - Call Rate
      - Account Visits
   + Messages
      - Inbound
      - Outbound

Those at the bottom of the tree branch are links. I have created a property in the master document type of 'IsHelpPage' of type true false.

Unfortunately I can't pick up this property as I look through each page in XSLT. I have the following code:

<?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"/>


<!-- update this variable on how deep your site map should be -->
<xsl:variable name="maxLevelForSitemap" select="40"/>

<xsl:template match="/">
<div id="sitemap">
<xsl:call-template name="drawNodes">  
<xsl:with-param name="parent" select="$currentPage/ancestor-or-self::* [@isDoc and @level=1]"/>  
</xsl:call-template>
</div>
</xsl:template>

<xsl:template name="drawNodes">
<xsl:param name="parent"/>
<xsl:if test="umbraco.library:IsProtected($parent/@id,
 $parent/@path) = 0 or (umbraco.library:IsProtected($parent/@id, 
$parent/@path) = 1 and umbraco.library:IsLoggedOn() = 1)">
<ul id="navigation"><xsl:for-each select="$parent/* [@isDoc and string(umbracoNaviHide) != '1' and @level &lt;= $maxLevelForSitemap]">
<li>
  <xsl:value-of select="./data [@alias = 'IsHelpPage'] = 1"/>
    <xsl:if test="./data [@alias = 'isHelpPage'] != '0'">yes
      <a href="{umbraco.library:NiceUrl(@id)}">
        <xsl:if test="$currentPage/@id = current()/@id">
          <xsl:attribute name="class">selected</xsl:attribute>
        </xsl:if>
        <xsl:value-of select="@nodeName"/>data [@alias = 'IsHelpPage']
      </a>
    </xsl:if>

  <xsl:if test="count(./* [@isDoc and string(umbracoNaviHide) != '1' and @level &lt;= $maxLevelForSitemap]) &gt; 0">   
    <xsl:call-template name="drawNodes">    
      <xsl:with-param name="parent" select="."/>    
    </xsl:call-template>  
  </xsl:if>
</li>
</xsl:for-each>
</ul>
</xsl:if>
</xsl:template>

</xsl:stylesheet>

Each time the value of the IsHelpPage property is false.

Any help on this would be greatly appreciated.
