AW: [xsl] Selection of every second node

[Conny Kreyßel <Conny dot Kreyssel at INTER-FORUM dot DE>]

Year this works, thanks.

But now I have another question. 

I would now apply a attribute (type="disc") in the "childs" template (<li>)
if the on every second parent entry (<node>) like this:

<root>
	<node>
		<another>1</another>
		<another>1</another>
		<another>1</another>
	</node>
	<node>
		<another>2</another>
		<another>2</another>
		<another>2</another>
	</node>
	<node>
		<another>3</another>
		<another>3</another>
		<another>3</another>
	</node>
	<node>
		<another>4</another>
		<another>4</another>
		<another>4</another>
	</node>
</root>

<xsl:template match="node">
	<ul>
		<xsl:apply-templates select="another" />
	</ul>
</xsl:template>

<xsl:template match="another">
	<li>
		<xsl:if test="boolean(parent::node()[(position() mod 2) =
0])">
			<xsl:attribute name="type">disc</xsl:attribute>
		</xsl:if>
		<xsl:value-of select="." />
	</li>
</xsl:template>

The Result should be:

<ul>
	<li>1</li>
	<li>1</li>
	<li>1</li>
</ul>
<ul>
	<li type="disc">2</li>
	<li type="disc">2</li>
	<li type="disc">2</li>
</ul>
<ul>
	<li>3</li>
	<li>3</li>
	<li>3</li>
</ul>
<ul>
	<li type="disc">4</li>
	<li type="disc">4</li>
	<li type="disc">4</li>
</ul>

Can you help me. My template doesnt work - I dont know why?


Thank you

COnny
