Re: [xsl] removing comma from within sum command

this is the current version of the xsl  (each value and sum for the remaining columns have been removed for 
this email):

the exslt reference: exslt="http://exslt.org/common"; can be added, but the question is: where 
would your example for the x variable and subsequent node-set be placed so that all columns and 
totals can be displayed? Does the for-next need to be removed from the "x" variable?

Thanks,
Dmitri

> s there a way to remove commas from the Charge node in this select?

Not in pure XSLT 1, no.

in XSLT 1 sum() can only be applied to text that directly occurs in the
source, if you need to do any transformation before summing you have to
go back to your original plan of using a recursive template.

Or simpler (but probably a bit less efficient) if your processor has a
node-set extension first transform the source into a variable removing
commas but not doing a sum, then sum this new node set.

<xsl:variable name="x">
<xsl:for-each select="Trade/Step
   [concat(substring(MinFlowDate,7),substring(MinFlowDate,1,2),substring(MinFlowDate,4,2))>=
concat(substring($global,7)+3,substring($global,1,2),substring($global,4,2))]

   [concat(substring(MinFlowDate,7),substring(MinFlowDate,1,2),substring(MinFlowDate,4,2))<
concat(substring($global,7)+6,substring($global,1,2),substring($global,4,2))]
   /Charge">
<charge><xsl:value-of select="translate(.,',','.')"/></charge>
</xsl:for-each>
</xsl:variable>

</xsl:variable>

<xsl:value-of select="format-number(sum(xx:node-set($x/charge),
'###,###,##0')"/>
