Re: [xsl] adding numbers

[David Carlisle <davidc@xxxxxxxxx>]

  <xsl:when test="contains(name(.), 'sub3') " >

usually best not to use name() use

<xsl:when test="self::sub3" >

  the problem i need to add  to x and y  within the element sub3 all the
  priviouse x(s) and y(s) in last position  of the elements  sub2 and sub1
  sub0 but could be more then these 3 elements

something like
<x><xsl:value-of select=". + sum(preceding-sibling::*[self::sub1 or self::sub2]/x[last()])"/></x>
