I have a DVWP that displays groups of data. For each group, I've got a sum of one of the columns. This sum exists in the group footer in a template called dvt_1.groupfooter0.
<xsl:variable name="mySum" select="sum($nodeset/@myQuantity)"/>
Is there any way to filter out groups depending on this sum (e.g. if the sum is negative). I don't think that the "XSLT Filter" for the DVWP will work, since it appears to filter prior to grouping...so this doesn't work:
[sum(@myQuantity) > 0]
The above discards individual rows for which myQuantity is negative.
