Hi all,

I hope you can help. i wonder if there is a function in xsl that does the
same as ABS(). So it has to look
for the absolute value of a variable.

I would like to do this:

<xsl:attribute name="href">showGroup.jsp?sortBy=<xsl:choose>
	<xsl:when test="($sortBy=1) or ($sortBy=-1)">
		<xsl:value-of select="-$sortBy"/>
	</xsl:when>
	<xsl:otherwise>
		1
	</xsl:otherwise>
	</xsl:choose>
</xsl:attribute>
 i would like to replace "<xsl:when test="($sortBy=1) or ($sortBy=-1)">"
with something like this:
<xsl:when test="abs($sortBy)">

Is this possible?

Thnx

Hervé
