Or:

<xsl:if test="string(.)">....</xsl:if>

Unfortunately, unless Matt has stripped whitespace, there may be some 
whitespace around to throw this off. So:

<xsl:if test="normalize-space(.)">....</xsl:if>

(But to avoid copying the empty nodes, Matt's going to have to traverse 
step-by-step only copying the ones that have non-empty string values ... no 
copy-of. Time for modes!)
