Xpath problem -follow up

Hi All,

After having worked with XSL for months I thought I am able do everything
but I admit I am stuck with a simple problem.

Here is  the xml file

<parent>
	<child>
	<child>
	<child>
</parent>
<parent>
	<child>
	<child>
	<child>
</parent>

xsl style sheet is structured in the following way (simplified version,
omitted xsl:)

<for-each select="parent">
<td>
	<call-template name="color">
	<value-of select="parent">
</td>
	<apply-templates select="child">

</for-each>

<template match="child">
<td>	
	<call-template name="color">
</td>
</template>

<template name="color">
	<xsl:choose>
		<xsl:when test=" [problem xpath here]position() mod 2">
			<xsl:attribute
name="class">lightregion</xsl:attribute>
</xsl:when>
		<xsl:otherwise>
			<xsl:attribute
name="class">darkregion</xsl:attribute>
		</xsl:otherwise>
	</xsl:choose>
</template>

in this case the case statement works (even/odd numbers) based on the
location of <child> element.

Since the design requires such an output

parent child child child (pink color)

parent child child child (blue color)

parent child child child (pink color)

<child> elements should pick up the same class attribute as the <parent>
element

I wanted to avoid code duplication (case statemnet) and tried to write a
jeneric one. Therefore I used a name template to be used in several places.

So the question is, how can I write an xpath for the <when test> element so
when it is called in the <parent> element loop it will check the condition
and when it is in the <child> loop it will check its <parent> element's
condition.

Any suggestions, ideas???

Thanks
