Hi everybody and thanks for the latest response,
I have created a key
<xsl:key name="detalleanno"
match="/PENSIONES/DETALLE_PENSION"
use="/PENSIONES/DETALLE_PENSION/ANNO" /> I would like to get
the sum of APORT_EMP during a year. I am trying with the
following expression: <xsl:value-of
select="sum(key('detalleanno',ANNO)/APORT_TRAB)"/>, but i
always get the sum of all the years and i only want the
values of a year. Could anyone give me an advice? thanks
The 'use' attribute of xsl:key is relative to the 'match' attribute, so
you will need to use:
<xsl:key name="detalleanno" match="/PENSIONES/DETALLE_PENSION"
use="ANNO" />
cheers
andrew
