Hi Thanos,

The following XSLT should do what you are looking for...

<!--Test to make sure some categories exist-->
<xsl:if test="$currentPage/ancestor-or-self::*[@isDoc and @level=1] /Forum//ForumCategory">
    <!--Loop through the categories-->
    <xsl:for-each select="$currentPage/ancestor-or-self::*[@isDoc and @level=1] /Forum//ForumCategory">
        <!--Put your HTML markup here-->
        <p><a href="{umbraco.library:NiceUrl(.)}"><xsl:value-of select="./@nodeName" /></a></p>
    </xsl:for-each>
<xsl:if>

Basically, the first bit of the select is getting the root node (the homepage) then it's searching for a node with the document type 'Forum' then any 'ForumCategory' document types that reside under that at any level (this is why there's a double slash - searches all children, not just direct decendents).

If you only want to get the main forum categories then you'll want to change the select to...

$currentPage/ancestor-or-self::*[@isDoc and @level=1] /Forum//ForumCategory[forumCategoryIsMainCategory=1]

Hope that helps.

Tom

Thank you for your reply Tom.

I have created the following xslt.

<?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:template match="/">

<!--Test to make sure some categories exist-->

<xsl:if test="$currentPage/ancestor-or-self::*[@isDoc and @level=1] /Forum//ForumCategory">

    <!--Loop through the categories-->

<ul id="nforumCategoryList">

    <xsl:for-each select="$currentPage/ancestor-or-self::*[@isDoc and @level=1] /Forum//ForumCategory">

        <!--Put your HTML markup here-->

        <li><a href="{umbraco.library:NiceUrl(.)}"><xsl:value-of select="./@nodeName" /></a></li>

    </xsl:for-each>

</ul>

</xsl:if>

</xsl:template>

</xsl:stylesheet>

And I am getting an exception

System.OverflowException: Value was either too large or too small for an Int32. at System.Convert.ToInt32(Double value) at System.Double.System.IConvertible.ToInt32(IFormatProvider provider) at System.Convert.ChangeType(Object value.

Any ideas? It didn't work to skip testing of the xslt.

is working on a reply...
