Preceding siblings

[Jaysakthy Muthuvelu]

Hi there,
In zvon tutorial the following question has this answer 1,2,3,4 nodes.
Iam fine with 2,3,4 nodes since they r preceding siblings,but 1st node <BBB> is the parent of <ccc/>. How come they r telling it's the preceding sibling. Plz clarify me.

//CCC/preceding-sibling::*

<AAA>
<BBB> ------- 1
<CCC/>
<DDD/>
</BBB> ------
<XXX> ------- 4
<DDD>
<EEE/> ----------2
<DDD/> ----------3
<CCC/>
<FFF/>
<FFF>
<GGG/>
</FFF>
</DDD>
</XXX> -----------
<CCC>
<DDD/>
</CCC>
</AAA>
Thanks
shakthy

Hi Jay,
I think it is looking for last CCC element, from which BBB obviously is preceding sibling.
<AAA>
<BBB>
<CCC/>
<DDD/>
</BBB>
<XXX>
<DDD>
<EEE/>
<DDD/>
<CCC/>
<FFF/>
<FFF>
<GGG/>
</FFF>
</DDD>
</XXX>
<CCC> <------ last CCC Element
<DDD/>
</CCC>
</AAA>
Please corect me if I am wrong.

Thanks,
Arun

Arun is right!
BTW, _all_ the output is from the last CCC element.

No, they are not all from the last CCC element. See the more readable version follow:

<AAA> 
  <BBB> ------- 1
    <CCC/> 
    <DDD/> 
  </BBB> ------
  <XXX> ------- 4
    <DDD> 
      <EEE/> ----------2
      <DDD/> ----------3
      <CCC/> 
      <FFF/> 
      <FFF> 
        <GGG/> 
      </FFF> 
    </DDD> 
  </XXX>
  <CCC> 
    <DDD/> 
  </CCC> 
</AAA> 

BTW, please use "code" button UBB to format your code, which will certainly save yours and others time.
Thanks!

Roseanne,
Please be kind to check the following -

<AAA> 
   <BBB> ------- 1
       <CCC1/> 
       <DDD/> 
   </BBB> ------
   
   <XXX> ------- 4
      <DDD> 
          <EEE/> ----------2
          <DDD/> ----------3
          <CCC2/> 
         <FFF/> 
         <FFF> 
             <GGG/> 
         </FFF> 
     </DDD> 
   </XXX> -----------
   
    <CCC3> 
       <DDD/> 
    </CCC3> 
    
</AAA>  

and -

<?xml version="1.0"?>
<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml"/>

<xsl:template match="/">
Caused by CCC1 - 
   <xsl:apply-templates select="//CCC1/preceding-sibling::*"/>
<br/>  
Caused by CCC2 -  
   <xsl:apply-templates select="//CCC2/preceding-sibling::*"/>
<br/>     
Caused by CCC3 -    
   <xsl:apply-templates select="//CCC3/preceding-sibling::*"/>
 <br/>  
</xsl:template>
</xsl:stylesheet>  

Cheers,
Dan

Dan,
The problem is we don't have any text in the xml, which causes the undesired result. I changed the stylesheet to make it be able to tell some thing as well as well-formated XML.

Thanks for giving me a chance!

I think both of us are right. You for the explanation about the siblings and me about the output of ------- 1 and ----------2 etc.
Cheers,
