I am not sure if the following is a bug or my misunderstanding.. I am trying to use
the sum method to sum durations within a for-each-group but i get the following error
"Cannot convert string "PT2M30S" to a double" I
would have thought Sum would recognise the datatye Is this a bug? Can anybody suggest a
work around? <xsl:for-each-group select="CallTrans"
group-by="../DetailHeader/@ServiceHeader"> <xsl:value-of
select="NumberDialed"/>: <xsl:value-of
select="sum(current-group()/MinSec)"/>
</xsl:for-each-group> I also tried the following <xsl:value-of
select="sum(seconds-from-duration(current-group()/MinSec))"/>
but seconds-from-duration() only works in a single node not a nodeset

This would work as written if you were running in schema-aware mode with MinSec
typed as a duration. But if MinSec is untyped, you need to convert it explicitly to a
duration: sum(current-group()/MinSec/xs:dayTimeDuration(.)) Note that XSLT coding
questions which are not specifically related to Saxon are best asked on the xsl-list at
