Xslt sum of absolute values

[Juho Jussila]

Hi

I'm trying to calculate sum of absolute values using Xslt 1.0
and math:abs (http://www.exslt.org/math/functions/abs/index.html)

I thought this would work:
<xsl:value-of select="sum(math:abs(/A/B/C))"/>
Well it doesn't, because there are multiple C's.

Is there any nice trick how to do this, or do I have to use
for-each -loop?

Thanks in advance

sum(/A/B/C[. &gt; 0]) - sum(/A/B/C[. &lt; 0])

Ah, cuspy.
