Hi Jeni
you are so great, I love you!!!! You´re right. Another template made the
"wrong" recursion. Now everything is working fine.
One more question. Is it possible to find out in which level of topic I am?
The thing is, that I have 4 levels, The 4th level has to get another
hyperlink, because the 4th level is not a single page, it is the whole
accumulation of the 5th level topics is in one page, with html ancers.
position()=last() doesn´t work, because, if I only have 2 topics in each
other, the last topic element is not an element of the 4th level. So how
can I find out that I´m in level 4 of the nested topic elements.
Thank you
Take care Michael

Hi Michael,
It is that way, because I still used my old sitemap template, which
you recommended to replace with the sitemap template you wrote. So I
did replace also the sitemap template. And now, I get a stack
overflow error, when I try to generate the homepage.
That usually indicates infinite recursion, but I can't see anything in
the code I recommended that would give you infinite recursion. I
tried:
XML document:
<homepage>
<topic name="point1" filename="asdf">
<topic name="subpoint1" filename="asdf1">
<topic name="subsubpoint1" filename="asdf2">
<topic name="subsubsubpoint1" filename="asdf3" />
</topic>
</topic>
<topic name="subpoint2" filename="asdf4" />
</topic>
<topic name="point2" filename="asdf5" />
<topic name="point3" filename="asdf6" />
<topic name="point4" filename="asdf7" />
</homepage>
XSLT:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:output indent="yes" />
<xsl:template match="/">
<xsl:call-template name="sitemap" />
</xsl:template>
<xsl:template name="sitemap">
<ul>
<xsl:apply-templates select="homepage/topic" />
</ul>
</xsl:template>
<xsl:template match="topic">
<li>
<a>
<xsl:attribute name="href">
<xsl:for-each select="ancestor-or-self::topic">
<xsl:value-of select="@filename" />
<xsl:if test="position() != last()">/</xsl:if>
</xsl:for-each>
</xsl:attribute>
<xsl:value-of select="@name"/>
</a>
<xsl:if test="topic">
<ul>
<xsl:apply-templates select="topic"/>
</ul>
</xsl:if>
</li>
</xsl:template>
</xsl:stylesheet>
and got, as the result:
<ul>
<li>
<a href="asdf">point1</a>
<ul>
<li>
<a href="asdf/asdf1">subpoint1</a>
<ul>
<li>
<a href="asdf/asdf1/asdf2">subsubpoint1</a>
<ul>
<li>
<a href="asdf/asdf1/asdf2/asdf3">subsubsubpoint1</a>
</li>
</ul>
</li>
</ul>
</li>
<li>
<a href="asdf/asdf4">subpoint2</a>
</li>
</ul>
</li>
<li>
<a href="asdf5">point2</a>
</li>
<li>
<a href="asdf6">point3</a>
</li>
<li>
<a href="asdf7">point4</a>
</li>
</ul>
So I guess the problem is somewhere that you haven't shown us.
Cheers,
Jeni
