RE: more on Using apply-templates instead of for-each?

Thank you Tom and Wendell...getting much clearer...

Tom, since you've also used value-of, may I assume this is not a case where
I can use apply-templates? Is that because I want the items in table rows?

It is not much different (in this case), just some re-arranging.

<xsl:template match="safety">      
   <table border="1" width="100%" cellpadding="4">         
      <tr bgcolor="red" valign="bottom">
         <th align="left">
            <h3>SAFETY</h3>            
         </th>         
      </tr>         
      <xsl:apply-templates 
               select="numbered_list/listitem" mode='safety'/>
   </table>      
   <br />   
</xsl:template>

<xsl:template match='listitem' mode='safety'>
   <tr>               
      <td>                  
         <xsl:number level="multiple" format="1. " count="listitem" />
         <xsl:value-of select="." />               
      </td>            
   </tr>
</xsl:template>

Notice that I used a mode on the template for "listitem".  That is so
you can process other "listitem" elements that are not in a "safety"
block differently (in case there are any) - just use a template that
matches "listitem" but has a different or no mode.

In this example, thre is not much difference between the for-each and
the apply-templates approach.  It is much like using subroutines instead
of in-line code. In-line is fine for short bits of code, subroutines are
preferred for longer or more complex sections of code.  

 In other cases, the fact that the context is a single node (in
for-each) vs. a node-set (in apply-templates and call-templates) can
make quite a difference.

Did this answer your question?

Cheers,
