Recursive Templates

[LeeGath]

Hello

I am writing a web site and trying to create a generice template for a given set of XML data. My aim is to display the Hierachy of the current page. For Example SectionA > SubSectionC > SubSubSectionE.

My schema is designed so the Sections are recursive(I think) : -

<xs:element name=&quot;Sections&quot;>
<xs:complexType>
<xs:sequence>
<xs:element name=&quot;Section&quot; maxOccurs=&quot;unbounded&quot;/>
</xs:sequence>
</xs:complexType>
</xs:element>

I'm just at a bit of a loss as to how I display this in my XSL stylesheet. If I was using VB or some other language I would recursively call a procedure, and produce a string of the current section compared to where it sits in the hierarchy.

Does anyone know how to achieve this?

This is a simple implementation of a recursive template

consider the XML file below

--------------Sections.xml---------------------------

<Sections>
<Section name=&quot;A&quot; caption=&quot;Section A&quot;>
<Section name=&quot;1&quot; caption=&quot;Section 1&quot; />
<Section name=&quot;2&quot; caption=&quot;Section 2&quot; />
<Section name=&quot;3&quot; caption=&quot;Section 3&quot; />
</Section>
<Section name=&quot;B&quot; caption=&quot;Section B&quot;>
<Section name=&quot;1&quot; caption=&quot;Section 1&quot;>
<Section name=&quot;i&quot; caption=&quot;Section i&quot; />
<Section name=&quot;ii&quot; caption=&quot;Section ii&quot; />
</Section>
<Section name=&quot;2&quot; caption=&quot;Section 2&quot; />
<Section name=&quot;3&quot; caption=&quot;Section 3&quot; />
</Section>
<Section name=&quot;C&quot; caption=&quot;Section C&quot;>
<Section name=&quot;1&quot; caption=&quot;Section 1&quot; />
<Section name=&quot;2&quot; caption=&quot;Section 2&quot; />
<Section name=&quot;3&quot; caption=&quot;Section 3&quot; />
</Section>
</Sections>

-----------------------------------------------------
A simple HTML out put can obtained with
the stylesheet below:

--------------Sections.xsl---------------------------

<xsl:stylesheet xmlns:xsl=&quot;

http://www.w3.org/1999/XSL/Transform&quot;

version=&quot;1.0&quot;>
<xslutput method=&quot;html&quot; version=&quot;4.0&quot; />
<xsl:template match=&quot;/&quot;>
<xsl:apply-templates />
</xsl:template>
<xsl:template match=&quot;Sections&quot;>
<xsl:apply-templates />
</xsl:template>
<xsl:template match=&quot;Section&quot;>
<li>
<xsl:value-of select=&quot;@caption&quot; />
<xsl:if test=&quot;count(Section) > 0&quot;>
<ul>
<xsl:apply-templates />
</ul>
</xsl:if>
</li>
</xsl:template>
</xsl:stylesheet>

Thanks for that it's definitely helpful but I want to take it a step further.

How do I tract the hierarchy from the current section. For example if the current section is &quot;Section i&quot;. What I want to be able to do is display &quot;Section B > Section 1 > Section i&quot;

How would I do that in such a way that it would work for any number of levels.

Thanks

Result,

Thanks for your help whichman. I did your bit of code then used the ancestor-of instruction which allowed me to traverse back up the tree.

Cheers
