RE: Best practices

What I meant was the inexpensive way of processing all the nodes.
Since I have plenty of xml documents which will be processed.  If my
template match is going to whole tree, obviously it will take time and
finally it will impact on the performance.

Thanks to both of you for response.

Do you mean the way to address it in XPath?  One way would be to set the

context using for-each and then pick and choose what you need.

If you had prefixed text:

   <xsl:for-each select="lln[(_at_)objname='Folder']">
     <!--prefix stuff-->
     <xsl:value-of select="@id"/>
     <!--infix stuff-->
     <xsl:value-of select="@description"/>
     <!--infix stuff-->
     <xsl:value-of select="n/@name"/>
     <!--suffix stuff-->
   </xsl:for-each>

If you just wanted them grouped together, you could concatenate them
with 
spaces (or not):

   <xsl:for-each select="lln[(_at_)objname='Folder']">
     <xsl:value-of select="concat( @id, ' ', @description, ' ', n/@name
)"/>
   </xsl:for-each>

If you want to create an importable fragment with which you can
specialize 
the processing of each of the elements by an importing stylesheet with 
overriding template rules:

   <xsl:for-each select="lln[(_at_)objname='Folder']">
     <!--prefix stuff-->
     <xsl:apply-templates select="@id"/>
     <!--infix stuff-->
     <xsl:apply-templates select="@description"/>
     <!--infix stuff-->
     <xsl:apply-templates select="n/@name"/>
     <!--suffix stuff-->
   </xsl:for-each>

Do you mean the way to display it in appearance?  I like blue, myself.

I hope this helps!
