RE: [xsl] Using XPATH axis within a recursive structure to match a descendent node

["Pawson, David" <David.Pawson@xxxxxxxxxxx>]

Mike, I can't get this to work using saxon 8.3

xml
<gui>
     <load>
 ........................*0
        something
     </load>
     <p> blah
           <b>
                 blah
                    <load>
 ........................*1
                       else
                    </load>
                    <gui><load>
 ........................*2
                             <again/>
                          </load>
                    </gui>
           </b>
     </p>
 </gui>


XSL

 <xsl:template match="gui">
    <!-- <xsl:apply-templates select=".//load[ancestor::gui[1] is current()]"
/>  <br /> -->
    <p> <xsl:apply-templates select=".//load except .//gui//load" />  </p>
  </xsl:template>


  <xsl:template match="load" >
    [<xsl:value-of select="."/>] <br />
  </xsl:template>


The commented out version works,
but the one shown (gui template) doesn't, and I can't see why it shouldn't?


Any suggestions why please?
regards DaveP

    In XPath 2.0,

    .//load except .//gui//load

    or

    for $this in . return $this//load[ancestor::gui[1] is $this]


    In XSLT (1.0 or 2.0) you could write

    .//load[ancestor::gui[1] is current()]
