[xsl] Table alternate rows colors within xsl:sort

[Michael Tihon <michaeltihon@xxxxxxxxx>]

I would want to display a datagrid which lines colors
varies regarding the position (one line white, one
line gray, one line white, ...) AFTER an xsl:sort.

The problem is that the "<xsl:if test="position() mod
2 = 0"> won't work after a <xsl:sort> because the
position() function returns the position in the
original xml, not the in sorted nodes.

I can't use a variable because xslt do not allow to
increment it within my xsl:for-each

Do someone know a solution to this ?

<xsl:template name="list">
<xsl:param name="type"/>
<table class="table" cellpadding="2" cellspacing="1" width="100%">
	<xsl:for-each select="links/link">
		<xsl:sort order="ascending" select="name"/>

		<!--This won't work-->
		<xsl:variable name="i" select="$i + 1"></xsl:variable>

		<xsl:if test="@type = $type">
			<xsl:choose>
				<xsl:when test="$i mod 2 = 0">
					<tr>
						<td class="tablerow1"><xsl:value-of select="$i"/><a href="{url}"><xsl:value-of
select="name"/></a></td>
						<td class="tablerow1"><xsl:value-of select="url"/></td>
					</tr>
				</xsl:when>
				<xsl:otherwise>
					<tr>
						<td class="tablerow2"><a href="{url}"><xsl:value-of select="$i"/><xsl:value-of
select="name"/></a></td>
						<td class="tablerow2"><xsl:value-of select="url"/></td>
					</tr>
				</xsl:otherwise>
			</xsl:choose>
		</xsl:if>
	</xsl:for-each>
</table>
</xsl:template>

Regards,
Mike.
