Re: changing node names in XML

Counting children is inefficient; just check for the presence of any child node. 
Also, if there are no children, there will be no nodes against which to apply-templates, no?
> <xsl:template match="employee[count(child::*)=0]">
>         <leaf>
>                 <xsl:copy-of select="attribute::*"/>
>                 <xsl:apply-templates select="*"/>
>         </leaf>
