xsl if exists
> Something like this:
> 
>   <xsl:apply-templates select="elements[1]" mode="list">
>     <xsl:with-param name="pElements" select="elements"/>
>   </xsl:apply-templates>
> 
> Then the template to wrap the results in a "ul" is the following:
> 
>  <xsl:template match="element" mode="list">
>     <xsl:param name="pElements"/>
>     <ul>
>         <xsl:apply-templates select="$pElements" mode="single"/>
>    </ul>
>  </xsl:template>


Or in XPath 2.0 most generally:

     if(exists(x))
        then f(g(x))
        else ()
