Re: [xsl] finding position() in xpath 1.0

[David Carlisle <davidc@xxxxxxxxx>]

I think I mis read your requirement. the code I posted works so long as
there is at most one node with test="yes. If you have multiple such
nodes and need to select the preceding cousin of all of them,
Then...

//CELL[@test='yes']/../preceding-sibling::ROW[1]/CELL[position()=count(../following-sibling::ROW[1]/CELL[@test='yes']/preceding-sibling::CELL)+1]

<ROWS>
<ROW>
   <CELL id="a"/>
   <CELL id="b"/>   <!-- select this and only this-->
   <CELL id="c"/>
</ROW>
<ROW>
   <CELL/>
   <CELL test="yes"/>
   <CELL/>
</ROW>
<ROW>

   <CELL id="aa"/>
   <CELL id="bb"/>   <!-- select this and only this-->
   <CELL id="cc"/>

   <CELL test="yes"/>

  <xsl:template match="/">
    <xsl:copy-of select="//CELL[@test='yes']/../preceding-sibling::ROW[1]/CELL[position()=count(../following-sibling::ROW[1]/CELL[@test='yes']/preceding-sibling::CELL)+1]"/>
  </xsl:template>

$ saxon count.xml count.xsl
